A microlens reflector ( 200 ) and light coupler comprises a material transparent to light of a predetermined wavelength bound by an envelope with a curved section ( 202 ) and at least two non-parallel flat sections ( 204, 206 ), the curved section ( 202 ) operative to reflect internally light entering the component through one flat section ( 206 ), the reflected light directed to leave the component through its other flat section ( 204 ). The microlens reflector can reflect and couple light from one optical element into another optical element, e.g. from a waveguide into a detector, and from a light source into a waveguide. Arrays of integrated microlens reflectors ( 700 ) may be used to couple optical fibers to on-chip optical waveguides in NxM optical cross-connects and switches, providing simple, true 3-dimensional optical coupling architectures.
