P01–Design of a computer-generated waveguide hologram for integrated free space sensing

Liu T., Jiao Y., Bente E.

In this work we present a design of a computer generated waveguide hologram coupler with an ultra-long working distance and wavelength multiplexing in the near infrared. An approximation method to compute the scalar field from a detour phase hologram is presented. The accuracy is comparable to FDTD but it is achieved much faster. Coupling efficiency […]
