基于热光效应的1×4聚合物数字光开关(英文)
A 1×4 Polymeric Digital Optical Switch Based on the Thermo-Optic Effect
【摘要】 提出了基于热光型聚合物的集成有S弯曲光衰减器的1×4Y分叉数字光开关.利用开关与光纤阵列耦合用的S弯曲,将其设计成可变光衰减器,这使得器件更紧凑,并获得低串扰和大分叉角.在小于200mW的驱动功耗下,器件串扰可低至-35dB.
【Abstract】 We present a 1×4 Y-branch digital optical switch in which S-bend variable optical attenuators are integrated.The S-bend waveguides,which are always introduced to connect the switch and the standard fiber array,are made use of and designed as variable optical attenuators.A compact device with low crosstalk and larger branching-angle is obtained.The device is fabricated on the thermo-optic polymer materials,and the performance of the device is measured.With an applied driving power of less than 200mW,the device has a low crosstalk of less than -35dB at a wavelength of 1.55μm.
