Abstract: (6193 Views)
The main emphasis in developing DOS has been on achieving low crosstalk (CT). CT in the order of -30 dB is acceptable in conventional DOS and below that value is hard to achieve. Relatively low drive voltage (or power requirements) is also necessary to optimized DOS. This paper depicts the design of Y-branched digital optical switches (DOS) with optimized on-chip area coverage, reduced driving voltage and cross talk. The proposed switch is designed using channel profile of proton exchanged lithium niobate substrate. The electro-optic effect of the material has been investigated from the DOS operation.
Keywords: Digital optical switch, electro optic effect, crystal cut, proton exchanged lithium niobate.
