Broadening the photonic bandgap in adiabatic distributed-Bragg-reflectors
Shailja Sharma, Abhishek Mondal, Ritwick Das
Adiabatic following has been an widely-employed technique for achieving near-complete population transfer in a two-level quantum mechanical system. The theoretical basis, however,…

Increased pump acceptance bandwidth in spontaneous parametric downconversion process using Bragg reflection waveguides
K. Thyagarajan, R. Das, O. Alibart +3
In this paper we show that by suitably tailoring the dispersion characteristics of a Bragg reflection waveguide (BRW) mode, it is possible to achieve efficient photon pair generati…
