Abstract:
An on-chip broadband radiation source, and methods for its manufacture such that a photonics IC comprises an optical waveguide such as a semiconductor waveguide, a thin III-V material membrane with absorption capability for absorbing an optical pump signal induced in the waveguide. The III-V membrane comprises a LED implemented therein. The photonics IC also comprises a coupling means between the waveguide and the membrane. The device provides a broadband radiation source at a wavelength longer than the wavelength of the transferred radiation. The broadband signal can then be coupled out through the waveguide and used in the chip.

Claim (Index 28):
A method for manufacturing a photonics integrated circuit, the method comprising:\n obtaining a substrate comprising at least one optical waveguide, combining III-V material with said optical waveguide so as to form a LED on the optical waveguide, wherein the method furthermore comprises introducing a coupling means in the at least one optical waveguide or the III-V membrane for transferring an optical pump signal from the optical waveguide up to the III-V membrane, and wherein combining the III-V material with the optical waveguide comprises creating a III-V membrane with a thickness between \u03bb/20*n 1  and \u03bb/2*n 1 , where \u03bb is the operating wavelength and n 1  the refractive index of the III-V membrane material, and having an absorption capability for absorbing the optical pump signal transferred up to the III-V membrane so as to pump the LED structure thus inducing broadband radiation at a wavelength longer than the wavelength of the optical pump signal.
