“…From the first demonstrations of slow-light propagation in ultra-cold atomic gasses 1 , solid-state Ruby 2 and photonic crystal (PhC) structures 3 , focus has shifted to applications, with slow light offering the ability to enhance and control light-matter interactions. The demonstration of tuneable delay lines [4][5][6] , enhanced nonlinearities 7,8 and spontaneous emission 9 , enlarged spectral sensitivity 10 and increased phase shifts illustrate the possibilities enabled by slow-light propagation, with microwave photonics emerging as one of the promising applications 11 .…”

Passive photonic crystals have been shown to exhibit a multitude of interesting phenomena, including slow-light propagation in line-defect waveguides. It was suggested that by incorporating an active material in the waveguide, slow light could be used to enhance the effective gain of the material, which would have interesting application prospects, for example enabling ultra-compact optical amplifiers for integration in photonic chips. Here we experimentally investigate the gain of a photonic crystal membrane structure with embedded quantum wells. We find that by solely changing the photonic crystal structural parameters, the maximum value of the gain coefficient can be increased compared with a ridge waveguide structure and at the same time the spectral position of the peak gain be controlled. The experimental results are in qualitative agreement with theory and show that gain values similar to those realized in state-of-the-art semiconductor optical amplifiers should be attainable in compact photonic integrated amplifiers.

“…In [48], for example, a delay element based on microring resonators in combination with graphene-based Mach-Zehnder interferometer switches is reported on a silicon nitride platform, demonstrating an optical delay up to 920 ps with optical loss less than 27 dB. Additionally, optical delay lines based on photonic crystal (PhC) waveguides [49,50], which allow flexible dispersion control, offer an attractive solution to support the realization of an on-chip signal processor. …”

“…The resulting RF filters show 3-dB bandwidths of several GHz, and sideband suppression of less than 10 dB in [64] and 12 dB in [65], respectively. In [50], a tunable and reconfigurable MWP filter based on a highly dispersive, low-loss 1.55 mm-long PhC waveguide delay line, which is characterized by an anti-symmetric shift of the first row of holes, has been presented. A tuning capability over the 0-50-GHz spectral band and a broadband operation bandwidth up to 50 GHz have been demonstrated for both notch and band-pass microwave filters.…”

Abstract:We describe recent progress in integrated microwave photonics in wideband signal processing applications with a focus on the key signal processing building blocks, the realization of monolithic integration, and cascaded photonic signal processing for analog radio frequency (RF) photonic links. New developments in integration-based microwave photonic techniques, that have high potentialities to be used in a variety of sensing applications for enhanced resolution and speed are also presented.

An overview of microwave photonic filters which are implemented in both incoherent and coherent operational regimes has been provided. For microwave photonic filters implemented in the incoherent regime, an incoherence light source usually a broadband light source such as a light-emitting diode source, an amplified spontaneous emission source, or a laser array is needed. Importance of negative coefficients and complex coefficients in photonic FIR filters is discussed in detail. In this paper various technique reported in the last few year for both incoherent and coherent regime microwave photonic filter are reviewed with significance on the system architecture of microwave photonic filters , photonic generation , processing of time-delay microwave photonic signals, tunable and reconfigurable microwave photonic filters. Complexity and challenges in system implementation for widespread use for practical application and possibilities of newer research in microwave photonic were also discussed.
