abstract: We demonstrate a III V/silicon hybrid external cavity laser with a tuning range larger than 60 nm at the C band on a silicon on insulator platform. A III V semiconductor gain chip is hybridized into the silicon chip by edge coupling the silicon chip through a Si3N4 spot size converter. The demonstrated packaging method requires only passive alignment and is thus suitable for high volume production. The laser has a largest output power of 11 mW with a maximum wall plug efficiency of 4.2% tunability of 60 nm (more than covering the C band) and a side mode suppression ratio of 55 dB >46 dB across the C band) The lowest measured linewidth is 37 kHz <80 kHz across the C band) which is the narrowest linewidth using a silicon based external cavity. In addition, we successfully demonstrate all silicon photonics based transmission of 34 Gbaud (272 Gb/s) dual polarization 16 QAM using our integrated laser and silicon photonic coherent transceiver. The results show no additional penalty compared to commercially available narrow linewidth tunable lasers. To the best of our knowledge, this is the first experimental demonstration of a complete silicon photonic based coherent link. This is also the first experimental demonstration of >250 Gb/s coherent optical transmission using a silicon micro ring based tunable laser.

abstract: An InGaAsP 1.5 mm laser, with one facet antireflection coated, has been incorporated into a diffraction grating external cavity. The lasing wavelength could be tuned over a 55 nm range about the centre wavelength of 1.5 mm by rotating the grating. Furthermore, it was found that the emission spectrum was extremely narrow; beat frequency measurements at 1523 nm against an HeNe laser showed it to be of the order of 10 kHz.

abstract: We demonstrate two novel hybrid lasers with the same III V ultrawideband gain medium. An hybrid III V/Si laser and its III V/SiO2 counterpart exhibit high fiber coupled output power without booster semiconductor optical amplifier (up to +13 dBm for III V/Si and +10 dBm for III V/SiO2) and a record tuning range (respectively, 95 nm and 66 nm) over the C and L bands with side mode suppression ratio greater than 35 dB.

abstract: A highly efficient silicon (Si) hybrid external cavity laser with a wavelength tunable ring reflector is fabricated on a complementary metal oxide semiconductor (CMOS) compatible Si on insulator (SOI) platform and experimental results with high output power are demonstrated. A III V semiconductor gain chip is edge coupled into a SOI cavity chip through a SiN(x) spot size converter and Si grating couplers are incorporated to enable wafer scale characterization. The laser output power reaches 20 mW and the highest wall plug efficiency of 7.8% is measured at 17.3 mW in un cooled condition. The laser wavelength tuning ranges are 8 nm for the single ring reflector cavity and 35 nm for the vernier ring reflector cavity, respectively. The Si hybrid laser is a promising light source for energy efficient Si CMOS photonic links.

abstract: A Si/III V hybrid laser has been a highly sought after device for energy efficient and cost effective high speed silicon photonics communication. We present a high wall plug efficiency external cavity hybrid laser created by integrating an independently optimized SOI ring reflector and a III V gain chip. In our demonstration, the uncooled integrated laser achieved a waveguide coupled wall plug efficiency of 12.2% at room temperature with an optical output power of ~10 mW. The laser operated single mode near 1550 nm with a linewidth of 0.22 pm. This is a tunable light source with 8 nm wavelength tuning range. A proof of concept laser wavelength stabilization technique has also been demonstrated. Using a simple feedback loop, we achieved mode hop free operation in a packaged external cavity hybrid laser as bias current was varied by 60mA.

abstract: Combining a semiconductor optical amplifier with a long and low loss external laser cavity made of dielectric integrated circuits has the advantage of obtaining extremely narrow laser linewidths. However, extending the cavity length also reduces the cavity mode spacing, and this spectral interval forms the fundamental limit for wavelength tuning without perturbing mode hops. The InP Si3N4 hybrid integrated laser we consider here has a mode spacing of 5 GHz. The external cavity consists of a phase section and a wavelength tunable filter, which is formed by two microring resonators. Via the phase section alone, mode hop free tuning was measured to be limited to 5 GHz as expected. We demonstrate that this range can be significantly extended, here to over 28 GHz, by tuning the phase section simultaneously and properly with the microring resonators. The results indicate that both a narrow linewidth and a broad mode hop free tuning range can be achieved with a chip based laser.

abstract: We present an integrated semiconductor dielectric hybrid dual frequency laser operating in the 1.5 \mu$m wavelength range for microwave and terahertz (THz) generation. Generating a microwave beat frequency near 11 GHz, we observe a record narrow intrinsic linewidth as low as about 2 kHz. This is realized by hybrid integration of a single diode amplifier based on indium phosphide (InP) with a long, low loss silicon nitride (Si$_3$N$_4$ feedback circuit to extend the cavity photon lifetime, resulting in a cavity optical roundtrip length of about 30 cm on a chip. Simultaneous lasing at two frequencies is enabled by introducing an external control parameter for balancing the feedback from two tunable, frequency selective Vernier mirrors on the Si$_3$N$_4$ chip. Each frequency can be tuned with a wavelength coverage of about 80 nm, potentially allowing for the generation of a broad range of frequencies in the microwave range up to the THz range.
