All-VCSEL based digital coherent detection link for multi Gbit/s WDM passive optical networks.
We report on experimental demonstration of a digital coherent detection link fully based on vertical cavity surface emitting lasers (VCSELs) for the transmitter as well as for the local oscillator light source at the receiver side. We demonstrate operation at 5 Gbps at a 1550 nm wavelength with record receiver sensitivity of -36 dBm after transmission over 40 km standard single mode fiber. Digi...
متن کاملCMOS Circuits for VCSEL - Based Optical
Electrical IO is becoming limited by copper interconnect channel losses that depend on frequency and distance. Package-to-package optical interconnects see negligible frequency-dependent channel losses, but data rates are limited by the intrinsic optical dynamics and electrical parasitics of the optical devices. This thesis presents 90nm CMOS front-end circuits which apply techniques to operate...
متن کاملVCSEL Proliferation
Since the commercialization of Vertical Cavity Surface Emitting Lasers (VCSELs) in 1996, Finisar’s Advanced Optical Components Division has shipped well over 50 Million VCSELs. The vast majority of these were shipped into the data communications industry, which was essentially the only volume application until 2005. The driver for VCSEL manufacturing might well shift to the increasingly popular...
متن کاملEvolution from TDM-PONs to Next-Generation PONs
An easy and efficient evolution method from a time-division multiplexing passive optical networks (TDM-PONs) to next-generation PONs is proposed and demonstrated. A single-type wavelength band combiner/splitter (WC) enables a simple and efficient evolution of TDM-PON maintaining the current PON infrastructure and wavelength plan. The feasibility of the proposed evolution architecture is shown b...
متن کاملPolarization-Insensitive Single Balanced Photodiode Coherent Receiver for Long-Reach WDM-PONs
In an access network based on a passive optical network architecture, coherent detection is attractive since it allows for high receiver sensitivity coupled with inherent frequency selectivity. Nevertheless, solutions employed in core networks are prohibitively complex and costly, requiring the optical complexity of the coherent receivers to be reduced to make them feasible for access networks....
