Bandpass & Edge Filters
Our filters efficiently separate and manipulate signals at closely spaced wavelengths in WDM applications with 200, 100, or even 50 GHz channel spacing.
Our filters are available in three-port packages for O-, C- and L-band applications as well as to multiplex 980 nm or 14xx nm pump laser wavelengths with a WDM, CDWM, or DWDM signal. They deliver high wavelength stability over a wide operating temperature range.
Bandpass, Edge, and Dichroic Filters
Get filters with flat passbands and very sharp cut-off and cut-on edge characteristics thanks to our decades of experience in thin film technology.
Low insertion loss
Wide and flat pass band
High adjacent channel isolation
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.
