Abstract :
A new quantum structure is proposed, the type 1.5 quantum well, which can be designed to modulate the optical transition oscillator strength with a very low field. The peaking of the oscillator strength and absorption with a low applied field is a practical advantage for modulator applications to reduce the drive voltage and increase the maximum absorption
