Abstract
The present disclosure is a method for manufacturing a quantum cascade laser device comprising the steps of: virtually injecting electrons having an energy value from zero to an energy value of a conduction band edge of the well layer into a starting barrier layer; calculating energy dependence of transmissivity of the electrons transmitted from the terminal barrier layer; calculating energy values of local maximum values and the number of the local maximum values; calculating eigenvalues and eigenfunctions by solving a Schrödinger equation for each local maximum value by using each energy value of the local maximum values as an initial value; and setting a laser oscillation wavelength on the basis of the eigenvalues calculated for each of the local maximum values.
