High-speed Measurement Technologies of AQ6370C Optical Spectrum Analyzer
The optical spectrum measurement is indispensable to the wavelength division multiplexing (WDM) technology that is increasingly being used in optical communications. Optical spectrum analyzers, which measure and analyze the optical spectrum of light that travels through optical fibers, are required to have high performance, functionality, and throughput as sophisticated optical communication de...
متن کاملOptical spectrometer at the nanoscale using optical Yagi-Uda nanoantennas
Here we present and analyze an optical spectrum analyzer at the nanometer scale that is able to distribute different frequency contents of the radiation of an optical dipole source into different directions in the space. The spectrum analyzer is composed of arrays of optical Yagi-Uda nanoantennas, forming relatively narrow radiation patterns operating at different frequencies. The optical Yagi-...
