Direct Modulation of Electrically Pumped Coupled Microring Lasers
Chi Xu, William E. Hayenga, Demetrios N. Christodoulides +2
We demonstrate how the presence of gain-loss contrast between two coupled identical resonators can be used as a new degree of freedom to enhance the modulation frequency response o…

Measuring the frequency response of optically pumped metal-clad nanolasers
Chi Xu, William E Hayenga, Mercedeh Khajavikhan +1
We report on our initial attempt to characterize the intrinsic frequency response of metal-clad nanolasers. The probed nanolaser is optically biased and modulated, allowing the emi…
