<p>The optical transmission is modulated by an electric signal. The transparent contact is irradiated by a laser light of a suitable wavelength and intensity, and the photo-luminescence intensity of the SC material is modulated by application of an alternating voltage to the contact biased in the blocking sense. The semiconductor has an np+ or a pn+ heterocontact consisting of a lightly doped SC material with direct band structure, and of a highly doped SC material with wider band spacing. The lighter doped component may include gallium arsenide.</p> |
