Oscillator strength and absorption cross-section of core-shell triangular quantum wire is computed for intersubband optical transition between ground state and first excited state. Kane type band nonparabolicity of first order is considered to study the shift of cross-section peak with incident radiation, and also of the oscillator strength with structural parameters. Results are compared with that obtained from parabolic overestimation. Results show that both oscillator strength and peak magnitude of absorption cross-section decreases with increasing dimension, and the rate is significant when nonparabolic dispersion relation is taken into account. Findings are important for designing optical emitter/detector using core-shell triangular quantum wire.
