ETOF (Etalon-based Tunable Optical Filters)
Perform pre-transmission and post-transmission ASE filtering and spectral shaping with our narrow passband filter, tunable over a 5 THz range in the C- or L-band.
Our narrowband ETOFs provide high extinction in an economical and compact package ideal for DWDM applications. They are based on clever use of the optical Vernier effect which uses two high-finesse etalons with slightly offset free spectral ranges.
ETOF – Etalon-Based Tunable Optical Filters
Use these filters for ASE suppression and spectral shaping. Their compact packaging enables easy integration into subsystems and transceivers.

SiC Circuitry Makes EVs Better
Coherent is one of the few companies worldwide with a complete, vertically integrated SiC manufacturing capability. We produce SiC wafers and epitaxy, all the way through power devices and modules. Furthermore, the unmatched quality with which we can produce SiC material makes Coherent virtually the only supplier positioned to successfully transition from the current standard wafer diameter of 150 mm up to 200 mm.
