Robust Light‐Emitting Devices: Laser‐Like Emission from a Sandwiched MoTe₂ Heterostructure on a Silicon Single‐Mode Resonator (Advanced Optical Materials 20/2019)

2D materials-based nano light sources have been developed for silicon photonics. In article number 1900538, Juntao Li, Yue Wang and co-workers report the room temperature laser-like emission from a sandwiched MoTe2 heterostructure on a silicon single mode resonator at 1319 nm. The authors observe much better environmental stability and demonstrate single-mode operation with a wide free spectral range. These results lend further support to the paradigm of 2D materials-based integrated light sources on a silicon platform.
