We demonstrate 32 Gbps per wavelength upstream record capacity for a FDMA-PON over 37 km of installed fiber and 32 dB ODN loss, adopting an innovative ONU based on a reflective Mach Zehnder modulator.
We report an electrically pumped AlGaInAs-silicon VCSEL using a high-contrast grating reflector on silicon. CW output power >1.5 mW, thermal resistance of 1.46 K/mW, and 5 Gb/s direct modulation is demonstrated.
We report monolithic, tunable 1550-nm HCG-VCSELs with 26.3 nm continuous tuning. Room temperature power of 2.3 mW, 85 °C power of 0.5 mW, and 10 Gb/s direct modulation over 100 km of fiber is demonstrated.
We report monolithic, tunable 1550-nm HCG-VCSELs with 26.3 nm continuous tuning. Room temperature CW power of >3.3 mW, and 10 Gb/s direct modulation over 100 km of fiber is demonstrated.
Long-wavelength VCSELs incorporating high-contrast gratings are demonstrated using planar, proton-implant structure, enabling low-cost manufacturing. We demonstrate 1550-nm VCSELs with single-mode CW operation up to 65C, 1.4 mW CW output at room temperature and error-free 2.5 Gb/s modulation.
<para> In normal injection-locked semiconductor lasers, the modulation signals are applied to the slave laser. In this paper, we show that modulating the master light before injection exhibits distinctive modulation dynamics and frequency response. We first present a detailed theoretical model and simulation results. Experimentally, we have successfully demonstrated both master amplitude and...
