High-Power (40mW) Full C-band Wavelength Tunable DFB Laser Array Integrated with Funnel Combiner

A wavelength tunable DFB laser array integrated with a wavelength-independent funnel combiner is fabricated. The laser module covers the full C-band wavelength range (~38 nm), and a high fiber output power of 40 mW (16 dBm) is obtained with a stable single mode
