Abstract
We have proposed and designed a monolithic integration of a novel antiresonant reflecting optical waveguide (ARROW) type demultiplexer and photodetector. The isolation was theoretically calculated to be -21.6dB between the wavelengths of 0.78 and 0.88 μm with a maximum detecting efficiency of 58 percent in a short demultiplexing/photodetecting length of 100 μm. We demonstrated its fundamental characteristic experimentally. This type of device can be applied to a wavelength division multiplexing (WDM) system with comparatively wide wavelength separation, e.g., 1.3- and 1.55-μm wavelengthsKeywords
