You are designing a quantum well laser as we briefly discussed in the lecture on the 1-D infinite square well. You want to make the well width such that an electron making a transition from the n=2 energy level to the n=1 energy level emits a photon of 1500 nm. Assuming the device can be modeled by the 1-D infinite square well, calculate the needed well width.
