Comparison of Anti-tracking Performance of Optical Circulators
Abstract: In this paper, we present two four-port optical circulators for TE and TM modes, respectively. Abstract: An 8-channel optical circulator array has been designed and fabricated using a high precision microlens array, which is aligned with a set of miniature optics including a bismuth-substituted YIG thin-film crystal and a rare-earth magnet. Compared to conventional single-channel. An optical circulator is a non-reciprocal passive component that routes light from one port to the next in a fixed sequence. Light entering port 1 exits at port 2. It does not travel backward through the device. Exploiting the recent technological development concerning Ce:YIG pulse laser deposition on silicon nitride platform, we design two integrated circulators, which can be used to implement several. Abstract— We present a path towards reconfigurable, electrically driven and integrated multiple-port optical circulators. They are technically related to Faraday isolators, and on a broader scale similar to electronic circulators.
