Reversible Optical Isolators and Quasi-Circulators Using a Magneto
In this work, we experimentally demonstrate the simultaneous one-way transmission and unidirectional reflection by using a magneto-optical Fabry–Pérot cavity and a magnetic field strength of 50 mT. An

High-isolation polarization-independent optical quasi-circulator with a
A high-isolation polarization-independent optical quasi-circulator with a simple structure is proposed. A Porro prism is employed in this kind of device for what is believed to be the first time. Because a

A mm-wave four-port quasi-optical circulator
A four-port quasi-optical circulator has been designed, built and tested for operation in the millimetre wave band. The specific circulator reported here was investigated over a 20 GHz bandwidth, centred

What is Quasioptics?
Quasi optical (QO) systems are often used in high-field EPR and DNP systems to separate the incident microwave beam from the reflected beam. Furthermore, quasi optics is a versatile technology to build
