Device possibilities for the MSW-optical collinear interaction

Experimental and theoretical results are given which show that desirable requirements for devices can be met by the magnetostatic-wave (MSW)-light collinear interaction. It has been shown experimentally that the interaction can produce narrowband, tunable passbands potentially useful for device functions in microwave filtering and light-wave frequency shifting. Theoretical calculations show a more narrow passband than that observed. To enhance coupling efficiency, the authors propose a multilayered structure with separate optical and microwave guiding layers. Example calculations for this structure show that 100% conversion lengths on the order of 1 cm at both 1.152 μm and 1.32 μm should be possible in low-loss films. These structures could be fabricated with present technology
