摘要: We demonstrate a novel wavelength-tunable hybrid external cavity silicon-based transmitter with integrated reflectivity tunable mirror. First, designs of laser based on reflective symmetric and asymmetric Mach–Zehnder interferometer-based mirrors are studied single- double-ring intracavity filters, respectively. Asymmetric configuration is used in order to increase the tuning range single-ring by more than 90%. Furthermore, adjustment mirror allows for control characteristics, such as threshold current, wall-plug efficiency, output power, linewidth. Finally, an ultracompact III–V/Si 28-nm then demonstrated design one ring modulator. successfully achieved modulation up 40 Gb/s transmission over 20 (100) km at 25 (10) Gb/s.
