Wavelength independent Faraday isolator.
A wavelength independent Faraday isolator has been built using an optically active rotator to compensate the dispersion of a 45 degrees Faraday rotator. Its isolation is better than 30 dB from 735 to 870 nm. Over this wavelength range the measured transmission in the forward direction is better than 80%. Dispersion, temperature, angular tolerance, and other factors affecting the isolation and forward transmission are discussed.
