Abstract
An ambient light filter structure and its response are disclosed. The ambient light filter structure comprises a silicon substrate, a first silicon nitride (Si3N4: 3200A+-200) component layer, a first silver (Ag: 285A+-35) component layer, a second silicon nitride (Si3N4: 920A+-50) component layer, a second silver (Ag: 285A+-35) component layer, and a third silicon nitride (Si3N4: 3500A+-200) component layer. Another ambient color filter structure is disclosed and further comprises a first sliver component layer, a first silicon nitride (Si3N4) component layer, second sliver (Ag) component layer, a second silicon nitride (Si3N4) component layer, a third sliver (Ag) component layer, a third silicon nitride (Si3N4) component layer, and a fourth sliver (Ag) component layer.
