发明名称 Optical filter comprising a multiple quantum well structure
摘要 <p>The multiple well quantum filter structure has an upper energy (E1) and lower energy level (E0) structure. The structure has a resonant absorption of an optical wavelength. Optical radiation excites charge carriers in the lower level when a voltage field is applied. The charge carriers are transferred to the upper level under the effect of optical radiation.</p>
