We report the fabrication of aspheric waveguide lenses on the InP/InGaAsP material system. A wide aperture (f/5) lens working at 1.5 times the diffraction limit is reported. Insertion loss below 1 dB is also measured. The lens is fabricated by a selective chemical etch of a planar waveguide and has potential applications in InP-based photonic integrated circuits.
