Abstract
An optical isolator that can easily be integrated with its source would significantly decrease
the cost of a laser diode module. A promising scheme consists of an amplifying
waveguide covered with a magnetized ferromagnetic metal. Earlier, we demonstrated this
concept experimentally. Here we report on the optimization of the isolator. Magneto-optic
waveguide calculations revealed a subtle interplay between the waveguide dimensions,
the cladding material and the properties of the metal film. Our experimental result of
12.7dB optical isolation combined with full compensation of the internal loss is the best
ever obtained. With this performance practical implementation is now within reach. Related Research Topics
