摘要： A light generating system that comprises a narrow evacuated slot defined between at least two high index contrast waveguide elements. The apparatus can be fabricated using a material such as a SOI wafer having an oxide layer thickness of the order of 1 micron and a top silicon layer thickness of the order of 100-150 nm. Electrode contacts are provided to at least two waveguide elements fabricated in the top silicon layer, each waveguide element having a thickness comparable to the top silicon layer thickness, a width of some hundreds of nm, and having a slot having dimensions in the range of 50-200 nm defined therebetween. The length of the slot is at least as long as the slot width. Charged particles, such as electrons, that are emitted and accelerated across the slot by an applied electrical signal provide a source of photons as a consequence of being accelerated and/or decelerated.

摘要： An all-optical sampling device using four-wave mixing in third-order optically nonlinear materials is described. The four-wave mixing based sampler comprises a waveguide combiner, which adds a gate optical signal to a signal of interest to be sampled. In a four-wave mixing region, a sampled signal at the output optical frequency is produced. All of the optical signals are sent to a passive optical filter, which preferentially discards the gate and signal optical frequencies, but preserves the sampled signal at the output optical frequency. The sampled signal at the output optical frequency can be observed, displayed, recorded or otherwise manipulated.

摘要： Radiation detection systems and methods. In one approach, optical radiation can be detected by using the radiation to be detected as input to a high index contrast waveguide modulator that modulates a wavelength of light that falls within the detection band of a detector. In another approach, the optical radiation that is to be detected is combined with a high power CW boost mode signal in a waveguide, and the sum and/or difference frequencies are detected. In either approach, one can use grating couplers to couple the optical radiation of interest into a waveguide.
