7. a) What improvement can be attained if a planar GaAs LED is encapsulated in a transparent polymer of refractive index 1.5, if the reflection at the polymer-air interface is neglected? The reflective index of GaAs is 3.4. b) The outcoupling value is poor, and a number of techniques have been developed to improve this. Explain briefly.
