AI Article Synopsis
- - The paper presents a new type of integrated optical device that combines cyclic arrayed waveguide grating (AWG) and Mach-Zehnder interference (MZI) filters to improve data transmission between waveguides and photodiodes.
- - This device functions as both a multiplexer for upstream signals in the L-band and a demultiplexer for downstream signals in the C-band.
- - The integrated chip has achieved a low insertion loss of 6.0 dB, outperforming traditional separate devices, and features more stable reflecting mirrors compared to individual reflectors.
Article Abstract
The paper introduces a silica-on-silicon monolithic integrated cyclic arrayed waveguide grating (AWG) with Mach-Zehnder interference (MZI) filters and arrayed vertical reflecting mirrors in silicon to realize effective and stable optical transmission between waveguides and photodiodes. The cyclic AWG acts as both multiplexer over the L-band for upstream traffic and demultiplexer over the C-band for downstream traffic. The integrated chip, including AWG, MZI filters, and arrayed reflecting mirrors, has been made successfully with a 6.0 dB insertion loss, which is less than the discrete devices. At the same time, the arrayed reflecting mirrors are more stable than separate reflectors.
