Terabit/s super-channels are likely to become the standard for next-generation optical
networks and optical interconnects. A particularly promising approach exploits optical …

We report on the design, growth, and fabrication of InAs/InP quantum dash (QD) gain
materials and their use in lasers for optical network applications. A noise performance …

We have used an external cavity self-injection feedback locking (SIFL) system to
simultaneously reduce the optical linewidth of over 39 individual wavelength channels of an …

A sub-100 fs all-fiber broadband optical frequency comb seeded from a 12.5 GHz electro-
optic modulated pulse is presented. Combining pulse resha**, nonlinear mixing with …

We have developed an InAs/InP quantum dot (QD) C-band coherent comb laser (CCL)
module with actively stabilized absolute wavelength and power, and channel spacing of …

This manuscript introduces a 5G radio access network architecture concept based on ultra-
dense wavelength division multiplexing (UDWDM) and incorporating an optical fronthaul …

Nyquist sha** UDWDM-PON combined with digital coherent optical systems has been
recently proposed as a promising technology for future optical access networks. In this …

We demonstrate a two-fold reach extension of 16 GBaud 16–Quadrature Amplitude
Modulation (QAM) wavelength division multiplexed (WDM) system based on erbium doped …

We study the limitations and their origins in the nonlinear effects mitigation in fiber-optic
communication systems. The carrier frequencies uncertainty and their stochastic variations …

We compare the timing jitter of a mode-locked InAs/InP quantum dash (QD) coherent comb
laser (CCL) with and without an external cavity self-injection feedback locking (SIFL) system …
