1.3-{micro}m laser diodes with spot-size converter for access networks
- NTT Opto-electronics Labs., Atsugi, Kanagawa (Japan)
A spot-size converted laser diode (SSC-LD), in which the spot size of oscillation light is expanded to match an optical fiber, is an attractive device providing low-loss coupling to the optical fiber or waveguide without lenses. Its large alignment tolerance is very effective to reduce the assembling cost of optical modules. Much research has been conducted on the SSC-LDs. However, the performance of the laser diodes inevitably deteriorates to some extent by integrating with a spot-size converter. For access networks applications, low threshold current, high output power, stable temperature characteristics and low cost are strongly required. This paper describes the design, the fabrication processes and characteristics of the newly developed 1.3-{micro}m laser diode monolithically integrated with a spot-size converter.
