Design of a red emitting GaAsP LED

Design Specs;

Emission Wavelength .6702 micro m.

optical power output Pout = 1mW

a. calculate current and voltage needed to obtain 1mW optical power output

b. calculate the extraction efficiency and find the current and voltage needed to obtain the desired optical output. Once you know the current density choose Area and Find Vf that will give you the desired current density and current (If= Jf x A= Jn A)

c. How would you improve your LED structure in terms of anti-reflection coating

d. how would you improve your design by incorporating TIP sturcture in terms of reduced loss due to internal reflection and and reflection of back photons. Assume Eg = 2.05 eV.
