摘要
采用非对称Ｘ结耦合器代替传统的Ｙ分支器，研制了ＧａＡｓＭａｃｈ－Ｚｅｈｎｄｅｒ型２×２光开光，得到了小于－２２．４ｄＢ的串音比和１２Ｖ左右的开关电压，器件的波导传输损耗小于７ｄＢ／ｃｍ。预计该器件可广泛应用于ＧａＡｓ开关列阵及高速光调制等领域。
In this paper, the asymmetric X junction is applied in GaAs Mach-Zehnder 2×2 optical switch instead of the traditional Y branch. The device operating at 1. 15μm has a 12V switching voltage and a crosstalk ratio less than-22. 4dB. This kind of device structure has been applied in the switching arrays and highspeed optical modulators.
