LiNbO3Wedges
A compact, highly efficient optical isolator
can be produced by mating a pair of
birefringent LiNbO3wedges together
with a Faraday polarization rotator. By
building on our comprehensive knowl-
edge of processing crystalline materials
for laser applications, Spectra-Physics has
positioned itself as the premier supplier of
LiNbO3 wedges for telecommunications
applications. We’re able to produce liter-
ally tens of thousands of wedges per day,
while maintaining tight optical and
mechanical tolerances, maximizing the
useable component clear aperture and
applying low loss, high efficiency broad-
band antireflection coatings.
