Abstract
Multi-wavelength laser arrays are critical for co-packaged optical interconnects, dense wavelength division multiplexing, high-performance optical computing, and sensors. Based on the reconstruction equivalent chirp (REC) technique, multiwavelength laser arrays (MLAs) are demonstrated with high channel count and high precision wavelength spacing. Recently, the photonic wire bonding (PWB) technique is applied to connect the MLA. But the lasers are mostly surface-emitted, such as the horizontal cavity surface-emitting lasers. In the practical applications, the lasers are usually edge-emitted, which is more difficult for the PWB technique. By using the photonic wire bonding technique, we connected a six-channel REC-based MLA, a PLC chip, and the fiber array. The lowest total transmission loss reaches to 7.8 dB. With further optimization of the PWB waveguide, the REC-based MLAs can be applied more easily, which is a potential solution for the requirement of high performance multi-wavelength light source in the relevant field.
