Paper Abstract

This paper describes the modeling of a 2×2 multimode interference (MMI) switch, with a channel profile of Titanium indiffused Lithium Niobate. Design novelty lies in its satisfactory operation for two wide optical windows (100nm each with centre wavelengths, λcentre of 1.3 μm and 1.55 μm) with low switching losses and crosstalk levels. Index tuned regions are optimized to achieve crosstalk levels of ≥ -18 dB and ≥ -14 dB for its operation in the wavelength range of 1.25 μm - 1.35 μm and 1.50 μm - 1.60 μm respectively. For either of these wavelength ranges, the switch losses (excess and insertion losses) are maintained lower than 1 dB.
