Hybrid encoding technique for the representation of the binary states of information, four-wave mixing in semiconductor optical amplifier (SOA) as frequency generator and cross-polarization rotation effect in semiconductor optical amplifier as a frequency converter are used to design all-optical universal logic gate NAND. The devices can perform ultrafast operation and easily integrable. The simulated...
A novel solar spectroscopic concept by combining a Shack-Hartmann (SH) and a Fabry-Perot (FP) interferometer is being developed to obtain high cadence solar observations of active as well as quiet regions. SH is used to generate multiple images of the same field-of-view (FOV) of interest. Whereas FP is used to tune these multiple images for different central wavelengths thus obtaining different points...
