CONSIDERATIONS TO KNOW ABOUT BIREFRINGENT CRYSTAL

For optical fibers and various waveguides, the excellence concerning uniaxial and biaxial does not apply, since the propagation direction is essentially determined by the waveguide.The reduced segment of your Michel-Levy chart (x-axis) marks the orders of retardation in multiples of about 550 nanometers. The area amongst zero and 550 nanometers is
