Abstract

An integrated optical interleaver has been demonstrated in SOI platform using large cross section single mode rib waveguide structures. The 2×2 device structure is in fact an unbalanced Mach Zehnder Interferometer formed by cascading two identical directional couplers. The device was designed to separate alternate ITU channels operating at λ ~ 1550nm. The fabricated devices have been characterized in terms of insertion loss, polarization and wavelength dependencies, channel extinction etc. The first prototype device operating at ~ 100 GHz ITU channel spacing has been observed to be slightly polarization dependent and a channel extinction of ~ 8 dB was recorded for TE polarization.
