What is Optical Circulator and its Applications?
>> Background History of Optical Circulator An optical circulator is a multi-port (minimum three ports) nonreciprocal passive component. The function of an optical circulator is similar to that of a microwave circulator—to transmit...Read more »
What is Fiber Optic Polarization Controller?
>> The Birefringence of Single Mode Fiber Circular core fibers whose axes are straight are not birefringent – that is, the two orthogonally polarized LP01 mode have the same effective indices. Bending such a...Read more »
