A Micro Integrable Tunable Laser Assembly (Micro ITLA) downsized by onethird (37.5×20.0 mm2) of the standard ITLA is developed. The Micro ITLA has the feature of improving a higher output power and a narrower spectrum linewidth while maintaining the function of the specification of the standard ITLA, and developing a compacted package module and a control circuit technology implemented with respect to the standard specification of the Micro ITLA. Furthermore, the spectrum linewidth of less than 300 kHz and the gridless wavelength output capacity (a minimum setting resolution: 0.1 GHz) were satisfied with a system requirement of more than 400 Gb/s.
