“…The thermal emission of the PC is observed in a narrow band of wavelengths controlled by this absorption profile. Previous experiments [9,10,11] and analyses were based on thermal emission in near-normal directions which is easy to measure. Emerging thermophotovoltaic (TPV) systems [5][6][7] utilize this novel selective wavelength emission.…”

We have simulated the angle-dependent absorption and thermal emittance of two dimensional metallic and metallodielectric photonic crystals (PCs) with rigorous scattering matrix methodswhere Maxwell's equations are solved in Fourier space. These metallic photonic crystals exhibit strong thermal emittance and absorption peaks in the normal direction. This peak splits into multiple peaks at larger and shorter wavelengths away from the normal direction. The thermal emission at different wavelengths is redistributed into different emission angles. There is partial suppression of photon emission at long wavelengths and enhancement at the shorter wavelength spectral range where the thermal emittance has a maximum. Angle-dependent measurements of the emission in metallo-dielectric photonic crystals are performed. Simulations compare well with these measurements and are consistent with the surface plasmon model. The strong dependence of the absorption with angle is very important for thermo-photovoltaic devices.

The development of plasmonic narrow-band thermal mid-IR emitters made from a conducting amorphous carbon composite is shown. These IR emitters have greatly improved thermal and mechanical stability compared to metallic emitters as they can be operated at 600°C in air without any degradation in performance. The emitted thermal radiation has a bandwidth of 0.5 m and can be set to the desired wavelength from 3 to 15 m by changing the surface periodicity. The periodically patterned devices have in-band emissivities significantly exceeding that of the non-patterned devices, constituting simple yet efficient radiation sources at this important wavelength range.The middle-infrared ͑mid-IR͒ spectral range ͑from 3 to 15 m͒ is of critical importance for thermal imaging, sensing and spectroscopy of chemical and biological agents, and environmental monitoring. 1 Unfortunately, very few radiation sources exist in this range and they are mostly in the development phase. Previously, narrow-band thermal radiation in the mid-IR from metallic photonic crystals and plasmonic two-dimensional ͑2D͒ structures was shown. [2][3][4][5][6][7][8][9] Three-dimensional metallic photonic crystals are difficult and costly to fabricate, making 2D structures attractive alternatives. Plasmonic thermal emitters ͑PTEs͒ based on periodically patterned metallic films provide tunable, narrow-band radiation, much narrower than from a black-body at the same temperature, constituting a simple yet efficient alternative to costly and complex light sources in the mid-IR. The metallic films typically used in PTEs are prone to oxidization and structural damage at high temperatures. As a result, current metallic PTEs cannot be operated above 350°C, reducing the maximum achievable output power and limiting the emitted wavelengths to the long part of the mid-IR. In addition, metallic films exhibit very high internal stresses that prevent the fabrication of free-standing membranes, resulting in slow switching ͑heating/cooling͒ and low power efficiency due to the large thermal mass of the substrates typically used to support these metallic films. Here we show the development of PTEs made from a highly conductive diamondlike ͑DL͒ material called nanoamorphous carbon ͑NAC͒ that overcomes these limitations, with significantly improved thermal and mechanical stability compared to their metallic counterparts. The emitted radiation has a bandwidth as small as 0.5 m and can be tuned to the desired wavelength by changing the periodicity of the surface pattern, constituting an efficient and low cost radiation source in the mid-IR.DL materials consist of carbon networks characterized by a high relative ratio of carbon in sp 3 states to sp 2 states and have important uses in applications that require high wear resistance, high temperature stability, large dielectric constants, and biocompatibility. 9-13 NAC is classified as a DL material; however, it contains two distinct structural net-works: a carbon network that also contains hydrogen atoms and a second network formed by ...

“…Several thermal emitter designs have been proposed using plasmonic structures [43][44], owing to their property of strong wavelength compression leading to sub-wavelength designs. Even though metal-based emitters produce an emissivity close to that of a black body, they feature small Qfactors, primarily due to relatively high losses for metals in the mid-IR frequency range.…”

A thermal emitter using a metasurface to tailor the emission spectrum in the mid-infrared for gassensing applications is demonstrated. The design consists of an array of high index dielectric elliptical pucks above a metal back-reflector. Using full-wave simulations in HFSS (Ver. 19.0.0), it has been shown that the achievable Q-factor (Q ≈ 150) in this structure is an order of magnitude larger than in plasmonic arrays (Q ≈ 16), attributed to the low-loss in the dielectric materials. Furthermore, the thermal emission properties of the structure can be engineered by manipulating Accomplishment of my thesis would not have been possible without the support of a few special people. I would like to acknowledge and thank my thesis supervisors Dr. Niall Tait and Dr. Shulabh Gupta from the bottom of my heart for providing consistent support and encouragement to complete this task. Specially going through and fixing the multiple drafts of my thesis and help with the journal papers. This project involved a lot of nanofabrication which is time consuming and requires a lot of expertise in terms of equipment usage and experience. I would like to extend my sincere thanks to Robert Vandusen, Angela M. Williams and Rodney Aiton for their continuous support during fabrication failures and encouragement and appreciation on my successes.

My deepest thanks goes to my family for being my continuous support in this journey. My Wife, Naureen Aqueel was always there to help me specially raising our two sons Muhammad Abdurrahman Ali and Muhammad Yasir Ali while I was working late hours at Carleton University working on my projects and writing my thesis. She was my constant support and encouragement and believed in me for successful completion of my project.
