A wide wavelength tunable quantum dot (QD) external cavity laser operating in the 1.31-μm waveband with a narrow line-width is successfully demonstrated. A high-density, high-quality InAs/InGaAs QD optical gain medium for the 1.31-μm waveband was obtained using a sandwiched sub-nano separator growth technique. A wide wavelength tunability of 1.265–1.321 μm and a narrow line-width of 210 kHz were successfully achieved using a compact and robust external cavity system constructed with multiple optical band-pass and etalon filters for active optical mode selection. The laser also achieved an error-free 10-Gb/s photonic data transmission over an 11.4-km-long holey fiber.
