“…In fact, the modulator has a positive chirp leading to the non-negligible power penalty. However, the penalty with increasing transmission distance is much smaller compared to the case of direct modulation [21], indicating much smaller wavelength chirp. The larger penalty at the shortest wavelength of 1546.92 nm within the whole 41-nm tuning range is mainly due to its lower signal power.…”

We report a widely tunable V-cavity laser monolithically integrated with an electroabsorption modulator (EAM). The device shows a 41-nm wavelength tunability covering 51 channels at 100 GHz spacing on the ITU grid, with a side-mode suppression ratio (SMSR) higher than 47 dB. Error-free transmission over 50 km standard single-mode fiber at 10 Gb/s is demonstrated at all wavelengths over the tuning range. The integrated EAM exhibits a dynamic extinction ratio higher than 12.5 dB. The bit-error-rate measurements show a power penalty less than 3 dB for 50-km transmission. The results demonstrate that this ultra-compact and regrowth-free electro-absorption modulated tunable laser can be a costeffective transmitter solution for DWDM metropolitan and access networks.

“…By introducing the concept of half-wave coupler into coupled-cavity lasers, excellent single mode selectivity has been achieved theoretically and experimentally [10], [11]. Vcavity lasers fabricated on multiple quantum well (MQW) wafers have shown good lasing and tuning performance at 870 nm [12], 1310 nm [13], 1550 nm [14] and 2810 nm [15], respectively. In the C-band, 31 channels of 100 GHz spacing can be tuned digitally at a fixed temperature and ~40 nm of wavelength tuning range can be achieved by the assistance of TEC temperature control with a good SMSR of about 38 dB [11].…”

We theoretically analyze and experimentally demonstrate improved half-wave couplers for widely tunable V-cavity lasers. An overlapping-image 6×6 MMI coupler and an aggregating-image 16×16 MMI coupler are investigated, which give optimal coupling phase and coefficient for achieving high singlemode selectivity in V-cavity lasers while producing a low loss. A single-electrode controlled tuning of 38 channels is achieved with channel spacings of 100GHz and 150GHz. By combining two single-electrode tuning segments at different temperatures, a wavelength tuning range of 52 channels from 1515nm to 1585nm is obtained, and the side mode suppression ratios (SMSRs) reach 45 dB.

“…Conventional widely tunable lasers, e.g., DFB laser array [11] and superstructure grating (SSG) DBR lasers [12] usually needs non-uniform gratings, multiple epitaxial growths and complex current control algorithms. In contrast, the V-cavity lasers (VCL) proposed in [13]- [15] does not require any complex grating or epitaxial regrowth. Furthermore, the VCL has a much smaller size and can use a single electrode for tuning over a wide range.…”

A monolithic 8×8 transmitter-router chip fabricated on InGaAlAs-InP multi-quantum well wafer for distributed wavelength routing network in the O-band with a channel spacing of 400 GHz is experimentally demonstrated. A tunable V-cavity laser (VCL) array, a cyclic-arrayed waveguide grating router (AWGR) and a semiconductor amplifier (SOA) array are integrated using the quantum-well intermixing (QWI) technique for its fabrication simplicity and cost effectiveness. A 200 GHz-spaced compact-size VCL is demonstrated with a 27 nm tuning range and a side-mode suppression ratio (SMSR) around 40 dB using a single-electrode controlled tuning. The chip output power is 24.6 mw. Measurement results of the transmitter-router chip show that all 64 input-output combinations have cyclic response spectra. After passing through the SOA with 80 mA bias current, an output power of about 9.6 mW and optical signal-to-noise ratio (OSNR) up to 39 dB have been measured. The demonstrated transmitter-router chip is fabricated on the same quantum well structure without requiring multiple epitaxial growth and complex grating fabrication. The characteristics of multi-wavelength and multi-port transmissions enable the distributed optical routing networks with flexible bandwidth allocation, which can find wide application in datacenters and high-performance computers.
