摘要： A waveguide optical gyroscope (WOG) is disclosed, which may include: an emitter; an integrated interferometer disposed on a silica planar lightwave circuit (PLC) and comprising a multilayer waveguide loop disposed in a first cladding material and interposed between layers of at least a second cladding material having an index of refraction lower than an index of refraction of the first cladding material; a pump source configured to pump the first cladding material with a signal that compensates for a propagation loss in the multilayer waveguide loop; and a micro-optic component configured to receive an output of the emitter and to guide the output into the integrated interferometer.

摘要： The present application is directed to a method of short pulse generation. The method includes the step of creating, via electrical circuitry in a master oscillator, a square wave pulse with a predetermined pulse repetition rate. The method includes the step of retiming the square pulse with a clock. The method includes the step of recovering an electrical signal from the retimed square pulse. Further, the method includes the step of sending the recovered electrical signal to a modulator for modulating an optical signal.
