Narrowband Waveguide Bragg Gratings with Fully-etched Side Corrugations and Large Fabrication Tolerance

Not Accessible

Your library or personal account may give you access

Abstract

Fully-etched cladding-modulated grating allows not only flexible control of the reflection response but also large fabrication tolerance. A reflection bandwidth of < 0.6 nm and a Bragg wavelength variation of within 1 nm is experimentally demonstrated.
