Research output: Contribution to journalArticlepeer-review


We investigate the wavelength insensitivity and fabrication error tolerance of the relative output amplitude and phase for a new type of optical coupler. This new coupler overcomes the long-length requirements of adiabatic couplers, yet achieves similar desirable properties. The three-space geometrical representation of coupled-mode theory, used as the design and analysis method, is presented and an example of a 3-dB coupler is examined.
