Classification: CPC G | IPC G

Claim 15:
16. A method for making an infrared (IR) source comprising:
forming a first dielectric layer over an electrically conductive layer;
forming a transparent electrically conductive layer over the first dielectric layer;
forming a second dielectric layer over the transparent electrically conductive layer;
forming a graphene layer over the second dielectric layer and having a perforated pattern; and
forming first and second electrically conductive contacts coupled to the graphene layer;
the graphene layer configured to emit IR radiation
in a frequency range based upon a voltage signal applied between the first and second electrically conductive contacts, and
with varying phase from adjacent portions of the perforated pattern of the graphene layer based upon the voltage signal applied between the first and second electrically conductive contacts.
