Grating filters for thin-film optical waveguides
The fabrication and evaluation of corrugation grating filters with reflectivities better than 75% and bandwidths less that 2 Å is reported. Grating filters were fabricated on glass waveguides using standard interferometric and ion-beam machining techniques and evaluated with a tunable dye laser. Mea...

| Zusammenfassung: | The fabrication and evaluation of corrugation grating filters with reflectivities better than 75% and bandwidths less that 2 Å is reported. Grating filters were fabricated on glass waveguides using standard interferometric and ion-beam machining techniques and evaluated with a tunable dye laser. Measured and calculated filter responses are found to be in excellent agreement. Tolerances for realizing ideal filter performances are given. |
