The laminate chip optical isolator suits high-speed and high-power transmitter applications. It is produced by adhering polarizers and a faraday rotator into one piece. The device is approximately one-third the size of conventional isolators (less than 0.5 mm sq). By assembling the chip isolator to a fiber pigtail tip (optical hybrid assembly), users can perform alignment of the isolator and fiber simultaneously.
