摘要：

Optical InP/GalnAsP directional coupler switches with a total length of 2 mm have been fabricated and operated by carrier injection. Switching is achieved at a very low injection current of 4 mA. For both switching states a crosstalk suppression exceeding 20 dB is obtained. In addition, the insertion loss estimated from the loss contributions of waveguides, bends and free carriers is as low as 1·3 dB. © 1990, The Institution of Electrical Engineers.
