介绍了一种宽电调谐范围（>73 nm）、窄带宽（约1.5 nm）的InGaAsP/InP可调谐定向耦合器滤波器的设计。该滤波器工作在电流注入和电折射两种情况下。这是迄今为止报道的半导体波导滤波器的最宽调谐范围，并且是在中等电流水平（约1.1 kA/cm/sup 2/）下获得的。如果包括热调谐，则调谐范围可以扩展到>80 nm。<<ETX>>
The design of a broad-electrotuning-range (>73 nm) and narrow-bandwidth ( approximately 1.5 nm) InGaAsP/InP tunable directional coupler filter that uses two vertically coupled asymmetric ridge waveguides is described. The filter operates with both current injection and electrorefraction. This is the widest tuning range reported to date for a semiconductor waveguide filter and is obtained with a moderate current level ( approximately 1.1 kA/cm/sup 2/). The tuning range can be extended to >80 nm if the thermal tuning is included.<<ETX>>
