It co...A simple and compact design of a delay waveguide unit for an optical serial-to-parallel conversion (OSPC) is proposed. It consists of a delay waveguide and Bragg reflectors and can supply optical path difference with one channel configuration for bit separation and unification in the time domain. In the unit, an identical delay waveguide can be used for several different carrier waves and the one delay unit is used twice in bidirectional operation. This leads to reduction in device complexity and size. The proposed unit is designed based on the silicon-on-insulator optical waveguide with eight apodized gratings for 40-Gbit/s 1:8 OSPC. The designed unit shows the potential to reduce the size of the delay part in the OSPC to about 1/8 of the reported approach, and good wavelength selectivity of eight gratings is confirmed with simulation.
