ABSTRACT We propose and demonstrate a tunable broadband photonic radio frequency (RF) phase shifter based on a silicon microring resonator. This scheme utilizes the thermal nonlinear effect of the silicon microring to change the electrical phase of the RF signal with a wide tuning range. A prototype of the phase shifter is experimentally demonstrated for a 40-GHz signal with a 0-4.6-rad tuning range.

    ABSTRACT: Silicon photonics leverages the optical, electrical and material properties of silicon and the mature complementary metal-oxide semiconductor (CMOS) nanofabrication technique to develop on-chip photonic integration, which has been making significant impacts in various frontiers including next-generation optical communications networks, on-chip optical interconnects for high-speed energy-efficient computing and biosensing. Among many optical structures fabricated on silicon chips, microresonators due to their high-Q resonances and small footprints play important roles in various devices including lasers, filters, modulators, switches, routers, delays, detectors and sensors. This paper reviews from a microresonator perspective some of the latest progress in the field, summarizes design considerations in various applications and points out key challenges and potentials.

    ABSTRACT: A photonic-assisted radio frequency phase shifter with direct current voltage control is proposed using a polymer-based integrated Mach—Zehnder modulator. A closed-form expression of radio frequency (RF) signal power and phase is given. Theoretical calculation reveals that by carefully setting the bias voltages, RF signal power variation lower than 1-dB and phase accuracy less than 3° can be achieved and are not degraded by perturbation of modulation index once the bias voltage drift is kept within −3% ~ 3%.

    ABSTRACT: We present a simple linear photonic technique to achieve fixed or time-varying phase shifts in microwave to terahertz frequency band signals. We show that the wavelength change of an RF modulated optical carrier within the operational band of a photonic filter with a step in the group-delay spectrum results in a broadband linear phase change in the RF signals. We demonstrate the concept experimentally using a simple fiber Bragg grating filter implementation in the microwave $K$ - and $Ka$ -bands, achieving up to 1500$^{circ}$ continuously tunable linear phase shifts within a 20-GHz bandwidth (15–35 GHz).
