Chip-Scale Microwave Photonic Signal Processing

Abstract

The use of optical technology can provide unprecedented performance to the generation, distribution, and processing of microwave. Recently, on-chip microwave photonics (MWP) has gained significant interests for its numerous advantages, such as robustness, reconfigurability as well as reduction of size, weight, cost, and power consumption. In this chapter, we review our recent progress in ultracompact microwave photonic signal processing using silicon nanophotonic devices. Using the fabricated silicon waveguide, silicon microring resonators (MRRs) and silicon photonic crystal nanocavities, we demonstrate on-chip analog signal transmission, optically controlled tunable MWP filter, and ultrahigh peak rejection notch MWP filter. The performance of analog links and the responses of MWP filters are evaluated in the experiment. In addition, microwave signal multiplication and modulation are also demonstrated based on a silicon Mach-Zehnder modulator in the experiment with favorable operation performance. The demonstrated on-chip analog links, MWP filters, microwave signal multiplication/modulation may help understand onchip analog signaling and expand novel functionalities of MWP signal processing.

Recent Trends and Advances of Silicon-Based Integrated Microwave Photonics

“…A key device for the generation of an arbitrary waveform in the SS-WTT system is therefore the spectral shaper that is designed to exhibit an amplitude spectral response with a shape corresponding to a scaled version of the temporal microwave waveform to be generated. Arbitrary waveform generation (AWG) is crucial to many RF tests, measurements and applications, including ultrawide-bandwidth wireless communications, and radar systems [3,14,40,74,128]. AWG is performed in electronic systems traditionally by oscillators based on two terminal devices (IMPATT, Gunn, quartz crystal, dielectric resonator) or three terminal devices (transistors) [3,14,40,74,128].…”

“…So far, a handful of excellent reviews on the MWP and IMWP topics have been presented by Chen [73], Wang [74], and Lee [75], and the review articles by Gasulla [38], Yao [22], and Marpaung [3], to name a few. In particular, the comprehensive review article by Marpaung et al in 2013 first covers the fundamentals of microwave photonics and then investigates the available platforms for IMWP.…”

Adaptive High Linearity Intensity Modulator for Advanced Microwave Photonic Links

“…"Photonic FPGA" is geared toward arbitrary function generation or function programmability in miniaturized form, which is essential in the full implementation of SDN. This technology is still in the early stages of development, but the growing numbers of demonstrations of on-chip optical processing have been reported and they look promising [27][28][29][30][31][32][33][34][35][36][37][38][39][40].
