The angular dependent element, may be, e.g., a dichroic filter, dichroic mirror, a cholesteric film, a diffractive filter, and a holographic filter.
This feedback can be non-optical, wherein the holographic filter output is used to actively control the wavelength through an external control mechanism.
Like shown in Fig. 1 (a), the incoming collimated light is diffracted by the volume holographic filter, and only a small fraction of the spectrum is affected.
