title = "Investigation of on-chip all-optical quantization and novel encoding method: Paving the way for optical analog-to-digital conversion chip",
abstract = "On-chip, all-optical quantization based on pulse spectral broadening in a 6 cm long chalcogenide waveguide and subsequent filtering is analyzed. Transfer function is obtained for an 8-level quantizer using 2 nm bandwidth filters. Matrix transformation is used to encode the quantized data into a gray-code. An all-optical implementation of the matrix transformation encoder is proposed based on all-optical Exclusive-OR (XOR) gate. Broad bandwidth supercontinuum generation in a chalcogenide waveguide and optical XOR gate based encoder paves the way for ultra-high bandwidth, high-resolution all-optical analog-to-digital conversion chip.",
