Abstract: QPSK (Quadrature Phase Shift Keying) is one of the digital modulation techniques that can encode two bits per symbol based on data that has been divided ...
Abstract: We fabricate an O-band membrane InGaAlAs electro-absorption modulator (EAM) integrated with a III-V/Si DFB laser on a Si photonics platform. The device exhibits 6-mW fibre-coupled output ...
