HIGH ISOLATION OPTICAL SWITCH, ISOLATOR OR CIRCULATOR HAVING THIN FILM POLARIZING BEAM-SPLITTERS |
摘要 |
An optical device for controlling the flow of light between ports includes a pair of polarizing devices, which employ frustrated total internal reflection and interference in a thin film coating to reflect p-polarized light and to transmit s-polarized light. Polarization-rotating devices are used to rotate the polarization plane of the s- and p-polarized light beams so as to create optical switches, isolators and circulators using these polarizing devices.
