 TM mode conversion are derived and computer calculations showing the characteristic of a quartz-substrate mode converter is obtained. A mathematical analysis of a gyrator using two mode converters in series is given and the schemes for an isolator, modulator, optical switch, and optical read-out devices are mentioned.
