We demonstrate the first semiconductor-optical fiber ring laser. The laser uses an InGaAsP traveling wave optical amplifier as the gain medium and a 1-m length of highly birefringent fiber as the feedback loop. Output coupling is provided by a fiber directional coupler. The highly birefringent fiber is used as an intracavity wavelength filter, enabling single-frequency oscillation with a narrow linewidth at a wavelength near 1.55 μm.

    A Si3N4 core waveguide, matched to a laser mode, is adiabatically tapered into a SiO2:P core waveguide, matched to a fiber mode. When used to couple the light from a semiconductor laser into an optical fiber, a loss of 3.1 dB is obtained, compared to a loss of 4.5 dB obtained with a lensed fiber.
