Optical components and subsystems: opportunities and challenges

摘要

This paper presents a brief review and discussion on the opportunities and challenges facing the optical components and sub-systems vendors. Specifically, this paper discusses some of the current components and sub-system development on the low loss CWDM filters, wavelength blockers, PLC switch arrays, wavelength selective switches, optical protection switching sub-systems, tunable filters and DCMs, and in addition, the fiber-coupled short-wavelength diode-lasers for medical applications.
