Enabling Technologies for Universal Convergence of NG
Broadband Networks
Abstract:
The
upcoming convergence of broadband networks would be described from the
viewpoint of devices, systems, network protocols and standards.
In the physical layer, examples of convergence will focus on cost-effective
components and novel hybrid silicon photonics in APD receivers and lasers. I
would describe our application to free space optics with such a novel APD
receiver subsystem with 45 dB margin via adaptive bandwidth provisioning and
Shannon capacity.
System-wise LAN/WAN convergence is exemplified in OTN ( G709 ) as the best
of both worlds in merging Ethernet and SONET with MPLS to guarantee QoS
performance of IP packets.
For ultimate convergence of wireless and wireline backhaul, I will conclude
with the latest developments of the hot IMS standard.
Biography:
Dr.
Michael Choy has been a twenty years technology veteran from Bell Labs. &
IBM (Watson). He specializes in bringing innovative concepts to prototyping
in the broadband optical subsystem and device physics arena. His diverse
interdisciplinary expertise spans from optical wireless laser transmitters
to novel APD photodiodes to fiber system network integration. His primary
expertise has been with Bell Labs Lucent where he has been the technology
lead on the system integration of the Metro 40 G system in Holmdel.
His pioneering achievements include the first application of the widely
tunable AOTF filter for WDM (late 80s) and the first demonstration of the
semiconductor amplifier multiple channel operation without crosstalk in
1992, almost a decade in advance of the contemporary demonstration.
Currently he is a co-founder and CTO of Luma-tech, specializing in video
compression to exploit triple play especially for DSL networks.
He has over 65 publications and 3 patents, two of which directly lead to
real products. His PhD is in Applied Physics, Stanford. His BS in
engineering physics is from Berkeley.
