4. A particular planar waveguide comprises a guiding layer of refractive index equal to 1.454 bound top and bottom by material of refractive index 1.450. a) What is the maximum thickness of this waveguide for single-mode operation at a wavelength of 1550 nm. b) If the thickness of the above waveguide is reduced to 70% of the maximum for single mode operation at 1550 nm, what is the new cut-off wavelength for single-mode operation?
