Abstract
We demonstrate compact SOI based arrayed waveguide gratings (AWG) for (de)multiplexing applications
with a large free spectral range (FSR). The large FSR is obtained by reducing the arm aperture pitch without
changing the device footprint. We demonstrate 4X100 GHz, 8X50 GHz and 12X400 GHz AWGs with an FSR
of 6.9nm, 24.8nm, 69.8nm respectively. We measured an insertion loss from -2.45dB for high to -0.53dB for low
resolution AWGs. The crosstalk varies between 17.12dB to 21.37dB. The bandwidth remains nearly constant and the non-uniformity between the center wavelength channel to the outer wavelength channel improves with larger FSR values. Related Research Topics
