Claims
- 1. An optical waveguide gyrator, a first mode converter, a second mode converter selected to form a complementary pair with said first converter, means forming an optical waveguide interconnecting said converter, a first optical waveguide pair forming a branched input to said first mode converter and constructed and arranged for selectively propagating TE waves in one branch and TM waves in the other branch, and a second optical waveguide pair forming a branched output from said second mode converter and constructed and arranged for propagating TE waves in one branch and TM waves in the other branch.
- 2. A gyrator as in claim 1 in which said complementary pair of mode converters consists of a longitudinal gyrotropic mode converter plus a longitudinal anisotropic mode converter and further including phase shifter disposed between said first and second mode converters.
- 3. A gyrator as in claim 1 in which said complementary pair of mode converters consists of a polar gyrotropic mode converter plus a polar anisotropic mode converter and further including a phase shifter disposed between said first and second mode converters.
- 4. A gyrator as in claim 1 in which said complementary pair consists of a longitudinal gyrotropic mode converter plus a polar anisotropic mode converter.
- 5. A gyrator as in claim 1 in which said complementary pair consists of a longitudinal anisotropic mode converter plus a polar gyrotropic mode converter.
- 6. A gyrator as in claim 1 further in which wave absorbing elements are disposed in one of said TE or TM waveguides of both said input and output pairs to thereby adapt said gyrator to function as an isolator.
