摘要

我们报道了高导热SiC薄膜激光器，由于高弛豫振荡频率和光子-光子共振频率，在25和55^{\circ}\math {C}$下，分别表现出98和84 GHz的平坦小信号响应。激光器能够半冷却的128 gbit /s NRZ传输。

Semi-cooled 128-Gbit/s NRZ operation of directly modulated membrane lasers on SiC substrate

We report membrane lasers on high-thermal-conductivity SiC exhibiting flat small-signal responses with 3-dB bandwidths of 98 and 84 GHz at 25 and $55^{\circ}\mathrm{C}$, respectively, due to the high relaxation oscillation frequency and photon-photon resonance frequency. The laser is capable of semi-cooled 128-Gbit/s NRZ transmission.
