Popis: A CW-mode optically controlled microwave switch (CW- mode OMS) on a coplanar waveguide (CPW) for both a standard and a new design with carrier-confinement structure is investigated. We exper- imentally show that it may not be possible to obtain less than 7 dB of insertion loss with the standard OMS, and the carrier diffusion limits the improvement of insertion loss in CW-mode operation. We present a new design with a carrier-confinement structure with silicon (Si) sub- strate etching to confine the optically generated free-carriers. Less than 2 dB of insertion loss is obtained with the new carrier-confined OMS. © 2003 Wiley Periodicals, Inc.
