A new AWG device has been designed and fabricated to implement the fractional Fourier transform and allow all-optical spectral and time signal manipulation. 12-channel OFDM to OTDM conversion has been experimentally demonstrated.


Integrated Photonics Research (2000), paper IFB2 | 2000

Mach-Zehnder-interferometer and arrayed-waveguide-grating integrated multi/demultiplexer with photosensitive wavelength tuning

Makoto Abe; Yoshinori Hibino; Takuya Tanaka; Mikitaka Itoh; Akira Himeno; Y. Ohmori

We successfully fabricated a 64 channel and 25 GHz spacing multi/demultiplexer by integrating a Mach-Zehnder interferometer and two arrayed-waveguide gratings (AWGs) in a PLC chip. The center wavelength of the AWG was precisely tuned with UV-laser irradiation at 193 nm.
