In the Spring 2000, CoreTek was acquired by Nortel Networks. CoreTek had been focused to improving optical system performance, reliability, and manageability by focusing on dynamic routing and management of the full spectrum of wavelengths utilized in WDM systems The firm provided the core components of hardware-enabled solutions that makes the All-Optical Network possible. - providing full wavelength conversion capabilities, wavelength routing, remote and dynamic wavelength provisioning, protection and restoration at optical level, and integrated per channel Quality of Service (QoS) monitoring. Solutions were based on an innovative implementation of MEMS technology - Micro-electromechanical Systems, tiny, integrated machines that are reliable, efficient, and inexpensive. With expertise also in dielectric thin film and active semiconductor laser diode technology, CoreTek has progressed this once speculative combination of technologies to a point of readiness for full-scale deployment in telecommunications networks. Recent achievements include: first use of MEMS technology for telecom applications; first tunable 1550 nm VCSEL; single mode laser with continuous tuning; highest output power for optically pumped single-mode lasers; fastest tuning speed for tunable lasers and filters and widest tuning range for tunable lasers and filters.
