We propose and demonstrate an optical 32QAM transmitter, consisting of two tandem IQ modulators driven by binary and 3-level electronics. Compared with the single-IQ modulator scheme requiring 6-level electronics, the complexity in electronics is reduced.

We present results on the relaxation dynamics of photoexcited carriers in MoS2 using optical-pump terahertz-probe spectroscopy. Our measurements indicate that carrier recombination is accelerated at low temperatures where defect-assisted recombination becomes more efficient.

Liquid crystal polarizers and waveplates are an enabling technology for large fusion lasers. While damage and replacement rates of liquid crystal optics remain remarkably low, degradation in polarizer performance has been noted and studied.
