Birefringent Wedges
We can provide birefringent crystal wedges used in fiber optical isolators (see the drawing below) and other applications
Specifications:
Crystal: YVO4, LiNbO3, BBO, Calcite and others
Aperture: 1.5 x 1.5 mm2 to 20 x 20 mm2
Length: 0.5 – 10 mm
Wedge angle: 0.2° - 20°
Flatness: l /4 @ 632.8 nm
Surface quality: 20/10 scratch and dig
AR-coating: R< 0.5% at central wavelength
As shown below, two birefringent wedges are used to construct a fiber optic isolator.
YVO4 crystal is superior to LiNbO3 and TiO2 crystals for
this application.
The standard size of YVO4 is 2 x 2 x 1 mm2 with 8° wedge angle,
AR-coated at 1550 nm or 1310 nm.
