摘要： A receiver, such as a miniaturized microwave-photonic coherent receiver (MMPR) is disclosed. The receiver includes an antenna to output an electrical RF signal received on a section of the antenna, a laser to produce an optical signal, a photonic modulator to receive the optical signal and the electrical RF signal and produce an EO-RF signal and to receive the optical signal and an electrical LO signal and produce an EO-LO signal, a signal combiner to provide a combined EO-RF and EO-LO signal and a photodiode to receive the combined signal and produce an IF signal. A method of detecting an object using the MMPR includes receiving an electrical RF signal corresponding to the object, outputting the electrical RF signal to a photonic modulator, modulating the electrical RF signal onto an optical carrier, demodulating the electrical RF signal to produce an IF signal and processing the IF signal.

摘要： An optical waveguide includes a first end surface; a second end surface, such that the second end surface is smaller than the first end surface; and a body extending between the first end surface and the second end surface, the body defining a complexly-contoured outer surface. An optical waveguide includes a first end surface; a second end surface, such that the second end surface is smaller than the first end surface; and a body extending between the first end surface and the second end surface, the body comprising one of a gradient-index material and a step-index material.
