TUNABLE CHANNEL DROPPING OPTICAL FILTER
Keywords:Optical Filter, Bend Fibers
The tunability for an optical notch filter by means of bending is studied. We consider a curved fourlayer slab waveguide as a model for a bent D-type singlemode optical fiber with a thin semiconductor film on its planar surfa
