摘要： The present invention discloses a device and a method for realizing spectral polarization-independent measurement based on a frequency domain depolarization structure. The device comprises a pump light source module, a depolarization module, an SBS effect generation module and a data acquisition and spectrum reconstruction module. The method comprises: emitting laser light having a fixed polarization state from the pump light source module; the laser light from an output end of the pump light source module passing through the depolarization module to become depolarized light; inputting the depolarized light as pump light into the SBS effect generation module to interact with signal light under test input from the outside into the SBS effect generation module; and after amplifying the signal light under test through the SBS effect generation module, performing data acquisition processing through the data acquisition and spectral reconstruction module and finally obtaining a spectrum of a signal under test. The present invention can eliminate the problems that the acquired spectral information is not accurate, the power measurement is not stable and the like when a spectral measurement device based on an SBS effect measures an input signal light having arbitrary polarization state, and has an important application prospect.

摘要： An optical circulator is a device that routes optical pulses from port to port in a predetermined manner, e.g. in a 3-port optical circulator, optical pulses entering port 1 are routed out of port 2, while optical pulses entering port 2 exit out of port 3 and optical pulses fed into port 3 exit out of port 3. Currently such an optical circulator is made of discrete components such as magnetooptic garnets, rare-earth magnets and optical polarizers that are packaged together with fiber optic elements. Disclosed herein is a different kind of optical circulator that is monolithically integrated on a single semiconductor substrate and that is applicable for the routing of optical pulses. The embodied invention will enable photonic integrated circuits to incorporate on-chip optical circulator functionality thereby allowing much more complex optical designs to be implemented monolithically.

摘要： A photonic microwave generation apparatus and a method thereof are disclosed. A comb-like optical signal generation module of the photonic microwave generation apparatus generates a comb-like optical signal. The comb-like optical signal is injected into a photonic microwave generation module of the photonic microwave generation apparatus, wherein the photonic microwave generation module includes a microwave generation laser. An optical power and a carrier frequency of the comb-like optical signal are adjusted so as to place the microwave generation laser in period-one nonlinear dynamics, and, at the same time, to phase-lock an oscillation sideband of the period-one nonlinear dynamics by one harmonic of the comb-like optical signal. Under such operation, the microwave generation laser emits an output optical signal that carries a microwave signal of a narrow linewidth and a stable frequency, which can be retrieved from the output optical signal by using a photodetector.

摘要： Exemplary apparatus and method can be availed for providing at least one electromagnetic radiation. For example, it is possible to provide at least one first electromagnetic radiation having a frequency that changes over time with a first characteristic period. Further, with at least one hardware arrangement, it is possible to receive and modify the first electromagnetic radiation(s) into at least one second electromagnetic radiation having a frequency that changes over time with a second characteristic period. The second characteristic period can be smaller than the first characteristic period. The hardware arrangement(s) can include a resonant cavity having a round-trip propagation time for the first electromagnetic radiation(s) that can be approximately the same as the first characteristic period.

摘要： A system and method includes a waveguide for guiding an energy received from a laser. A resonator couples with the waveguide. A signal generator (pump) generates a spatiotemporal pattern wave in the resonator. The spatiotemporal pattern wave produces a wave interaction. Where an interaction between the signal, the spatiotemporal pattern wave and the wave interaction produce linear non-reciprocal behavior in the signal wave.
