Abstract
An embodiment relates to a device comprising an optical pipe comprising a core and a cladding, the optical pipe being configured to separate wavelengths of an electromagnetic radiation beam incident on the optical pipe at a selective wavelength through the core and the cladding, wherein the core is configured to be both a channel to transmit the wavelengths up to the selective wavelength and an active element to detect the wavelengths up to the selective wavelength transmitted through the core. Other embodiments relate to a compound light detector.
