Abstract :
An alternative macrooptic design of crystal-type multiport optical quasi-circulator is proposed. A prototype of six-port optical quasi-circulator was fabricated and tested with insertion loss of 1.97 dB, and isolation of 39.6 dB. The advantages of this design include high performance, being polarization-independent , and resolved polarization-mode dispersion. In addition, the number of ports can be easily expanded.
