Single-mode Wavelength Flattened Couplers

Description

The Single-mode Wavelength Flattened (single-window Broadband) Couplesr employ Bandwidth-extending Technique (Asymmetrical Technique) to extend bandwidth up to ?40nm at 1310/1550nm channesl by changing the wavelength characteristics. In this broad range, the accurate coupling ratio can be obtained. Moreover, this kind of couplers can satisfy the requirements of Low Excess Loss, Low PDL, etc. Single-mode Wavelength Flattened (Single-window Broadband) Couplers have already been widely used for broadband light source, test instruments and broadband optic-fiber networks.
