“…based LEDs described by Nash et al 12 was approximately 0.02%. A much higher WPE of 0.15% has recently been reported in interband cascade light emitting devices with peak emission at 3.3 μm, 13 but this is still much lower than in LEDs operating at shorter wavelengths.…”

We have investigated the spatial and spectral characteristics of mid-infrared thermal emission from large area Chemical Vapor Deposition (CVD) graphene, transferred onto SiO2/Si, and show that the emission is broadly that of a grey-body emitter, with emissivity values of approximately 2% and 6% for mono- and multilayer graphene. For the currents used, which could be sustained for over one hundred hours, the emission peaked at a wavelength of around 4 μm and covered the characteristic absorption of many important gases. A measurable modulation of thermal emission was obtained even when the drive current was modulated at frequencies up to 100 kHz.

“…For some specialized spectroscopic chemical sensing applications and noninvasive analysis, broadband, incoherent radiation sources are preferred over single mode lasers due to their capability to cover a complete spectral absorption band of an analyte. Semiconductor light-emitting diodes emitting at wavelengths spanning 2-10 μm have been developed and commercialized [35][36][37][38][39]. Recently, interband cascade light emitting devices (ICLEDs, which are not strictly diodes) with 15 active stages reached a record continuous wave (cw) output power of ~1.6 mW when operated at T = 25 °C and I = 600 mA.…”

“…Figure 2 illustrates the collimated ICLED output power for different injection current levels, as measured by a power meter (Ophir NOVA II). Shown for comparison is the analogous power vs. current for an earlier 15-stage ICLED that was processed with the same 400 μm mesa diameter for the study reported in [39]. Since both ICLEDs emit in a Lambertian divergence profile, the measured optical powers depend on the efficiency of the collection optics.…”

Compact photoacoustic module for methane detection incorporating interband cascade light emitting device

et al. 2017

A photoacoustic module (PAM) for methane detection was developed by combining a novel 3.2 μm interband cascade light emitting device (ICLED) with a compact differential photoacoustic cell. The ICLED with a 22-stage interband cascade active core emitted a collimated power of ~700 μW. A concave Al-coat reflector was positioned adjacent to the photoacoustic cell to enhance the gas absorption length. Assembly of the ICLED and reflector with the photoacoustic cell resulted in a robust and portable PAM without any moving parts. The PAM performance was evaluated in terms of operating pressure, sensitivity and linearity. A 1σ detection limit of 3.6 ppmv was achieved with a 1-s integration time.

“…Therefore there is an interest in dispersive spectrometers using a broadband light source. A number of discrete opto-electronic light emitters and photodetectors have been demonstrated to realize such spectroscopic systems in the 3 -4 μm wavelength range [3][4][5][6][7]. The integration of such components on a photonic integrated circuit is essential for the miniaturization and cost reduction of such spectroscopic sensors.…”

Abstract:A compact (1.2 mm 2 ) fully integrated mid-IR spectrometer operating in the 3 μm wavelength range is presented. To our knowledge this is the longest wavelength integrated spectrometer operating in the important wavelength window for spectroscopy of organic compounds. The spectrometer is based on a silicon-on-insulator arrayed waveguide grating filter. An array of InAs 0.91 Sb 0.09 p-i-n photodiodes is heterogeneously integrated on the spectrometers output grating couplers using adhesive bonding. The spectrometer insertion loss is less than 3 dB and the waveguide-referred responsivity of the integrated photodiodes at room temperature is 0.3 A/W.
