Abstract

We proposed and experimentally demonstrated wavelength division (de)multiplexers (WDMs) utilizing the wavelength dispersive nature of self-imaging multimode interferometers. Proof-of-principle devices fabricated on the silicon-on-insulator platform operated as 4-channel WDMs with a free spectral range of $>90\mathrm{nm}$, an averaging cross talk of $<-20\mathrm{dB}$ for a $1\mathrm{nm}$ band, and an insertion loss of $<2.0\mathrm{dB}$. The potential for higher channel counts and smaller channel wavelength spacing was also predicted. This type of WDM is easy to design and fabricate. The underlying concept is applicable to all planar waveguide platforms.
