SUMMARYWe provide an overview of techniques for the photonic generation of arbitrary RF waveforms, particularly those suitable for impulse radio or multi-band ultrawideband (UWB)-over-fiber transmission, and chirped microwave waveforms, with an emphasis on microwave photonic filtering and optical spectral shaping followed by wavelength-to-time mapping. We discuss possibilities for integrating the various device and component technologies with silicon photonics.

“…As with the systems described previously, it is based on a FIR MPF. Partially degenerated four wave mixing (FWM) in a nonlinear medium is used to increase the number of optical carriers/taps [18]- [20]. In particular, at least N = 2M taps can be obtained starting from M sources.…”

“…The modulated optical signal is then launched to a MWP processor, in which it is suitably manipulated through photonic devices. Examples of realized MWP functionalities include microwave photonic filters (MPFs) [23][24][25], arbitrary waveform generation (AWG) [14,26,27], beam steering [28][29][30], and phase shifting [31][32][33][34]. The manipulated optical signal is finally converted back to the microwave domain in the receiver, which typically consists of a photodiode.…”

Multitude applications of photonic devices and technologies for the generation and manipulation of arbitrary and random microwave waveforms, at unprecedented processing speeds, have been proposed in the literature over the past three decades. This class of photonic applications for microwave engineering is known as microwave photonics (MWP). The vast capabilities of MWP have allowed the realization of key functionalities which are either highly complex or simply not possible in the microwave domain alone. Recently, this growing field has adopted the integrated photonics technologies to develop microwave photonic systems with enhanced robustness as well as with a significant reduction of size, cost, weight, and power consumption. In particular, silicon photonics technology is of great interest for this aim as it offers outstanding possibilities for integration of highly-complex active and passive photonic devices, permitting monolithic integration of MWP with high-speed silicon electronics. In this article, we present a review of recent work on MWP functions developed on the silicon platform. We particularly focus on newly reported designs for signal modulation, arbitrary waveform generation, filtering, true-time delay, phase shifting, beam steering, and frequency measurement.

“…As of now, there have been four projects involving college student participation and all projects explored using silicon nanowires (SNW) to build optical signal processing engines. Specifically, we have been exploiting four-wave-mixing (FWM) in SNWs in the implementation of microwave photonic filters (MPF) [16,17], in achieving wavelength conversion and multicasting [18][19][20] and in RF arbitrary waveform generation (AWG) [21], and we have investigated Bragg grating structures in SNWs [22].…”

As educators and researchers in the field of photonics, we find what we do to be very exciting, and sharing this passion and excitement to our university students is natural to us. Via outreach programs and college research funding, a new college and university collaboration has broadened our student audience: photonics is brought into the college classroom and research opportunities are provided to college students. Photonics-themed active learning activities are conducted in the college Waves and Modern Physics class, helping students forge relationships between course content and modern communications technologies. Presentations on photonics research are prepared and presented by the professor and past college student-researchers. The students are then given a full tour of the photonics university laboratories. Furthermore, funds are set aside to give college students a unique opportunity to assist the college professor with experiments during a paid summer research internship.
