In this paper, We reported an uncooled operation of a
directly-modulated 1270 nm, InGaAlAs multiple quantum
wells (MQWs) DFB laser with a high modulation
bandwidth at 45 °C (above 20 GHz). The presented device
possesses a non-return-to-zero transmission speed of 25
Gb/s with an eye-opening feature at room temperature
(25 °C).
