ACTIVE/PASSIVE MONOLITHICALLY INTEGRATED CHANNEL FILTERING POLARIZATION SPLITTER

Title:

ACTIVE/PASSIVE MONOLITHICALLY INTEGRATED CHANNEL FILTERING POLARIZATION SPLITTER

Document Type and Number:

Japanese Patent JP2005222048

Kind Code:

A

Abstract:

To provide a polarization splitter having active functions such as a laser, an amplifier, a modulator and a detector and the like monolithically integrated on a single chip together with passive functions such as wavelength multiplexing/demultiplexing, polarization control, and signal filtering.

An InP on-chip polarization splitter is proposed based on an arrayed waveguide grating that is composed of waveguides having birefringence. The polarization splitter also performs channel filtering and demultiplexing that is useful in WDM/DWDM applications. The required waveguide structure is formed using active-passive monolithic integration platforms, providing the integration of the polarization splitter with active devices as well as passive devices.
