[MD1-1] Watt-class Directly Modulated Photonic-crystal Surface-emitting Lasers for High-speed Free-space Optical Communications

○Takuya Inoue¹, Ryohei Morita^1,2, Susumu Noda¹ (1.Kyoto University, 2.Tohoku University)

We review our recent demonstration of directly modulated watt-class photonic-crystal surface-emitting lasers and their application to high-speed, high-power, free-space optical communications without transmitter lenses nor optical amplifiers.
