Photonic Communications Engineering
OPTI 500, Spring 2012, Lecture 1, PCE Introduction
Class Syllabus • Class is divided into three one credit parts
– Optical Transmitters and Receivers (OPTI 500D) – Photonic Integrated Circuits (OPTI 500E) – Optical Transmission Systems (OPTI 500F)
• Lectures to be given by primary instructor and “Guest Lecturers” (CIAN faculty, Industry Partners, and others) who will be invited to speak on specialized topics.
• Exams and homework will determine grade – 2 homework sets for each part D, E, and F count 40% – 1 exam for each part D, E, and F counts 60%

CIAN will enable the transformation of the Internet from a transport medium into
a web of services by creating new integrated optoelectronic technologies
CIAN’s Mission
Achieving our mission would impact: • Education (multi-media delivery, e-learning) • Healthcare (telemedicine) • Cyber presence and energy efficiency (telepresence/ telecommuting) • New business opportunities (e.g. entertainment)

• Network convergence refers to the use of both datacom and telecom protocols and hardware in the same network.
• The motivation is to share resources and to combine the flexibility of datacom networks with the high capacity and Quality of Service assurance of telecom networks
24
Network Convergence
OPTI 500, Spring 2012, Lecture 1, PCE Introduction
• The communication infrastructure has evolved so that complicated convergence schemes like this are widely used today
• People agree that simplification would be a good thing
