How Power Budget Calculations Affect Technology choices in Optical Communication
Seminar: Departmental | November 28 | 4-5 p.m. | 293 Cory Hall

Abstract: A key challenge in optical communication today is transporting ever larger bandwidths of data from one point to the other efficiently. Metrics used to judge efficiency of a solution are power consumed per bit, pJ/bit, physical space required for the optical interface Gb/s/mm2 , and cost of transport $/Gb/s. We will show how simple power budget calculations can be used to decide between technology choices to solve a optical transport problem. As an example, Silicon Photonic and VCSEL based solutions are compared for a short reach interconnect.
