Tunable Long Period Gratings

$2,500.00

Tunable long period gratings (TLPG) can be used to couple optical signals between symmetric modes and anti-symmetric modes with adjustable grating period and also the coupling strength (0 – 100 %). The mode coupling can take place between core modes and/or cladding modes in single-mode or multi-mode fibers. The TLPG has a wide tuning range for the grating period from 300 to 900 microns allowing the universal use of the device for wide range of wavelength for different types of fibers.

Features
