Symmetrical polarization splitter/rotator design and application in a polarization insensitive WDM receiver.
In integrated photonics, the design goal of a polarization splitter/rotator (PSR) has been separating the TE0 and TM0 modes in a waveguide. This is a natural choice. But in theory, a PSR only needs to project the incoming State Of Polarization (SOP) orthogonally to its output ports, using any orthogonal mode basis set in the fiber. In this article, we introduce a novel PSR design that alternati...
متن کاملPolarization splitter and polarization rotator designs based on transformation optics.
The transformation optics technique is employed in this paper to design two optical devices - a two-dimensional polarization splitter and a three-dimensional polarization rotator for propagating beams. The polarization splitter translates the TM- and the TE-polarized components of an incident beam in opposite directions (i.e., shifted up or shifted down). The polarization rotator rotates the po...
متن کاملIntegrated mode-evolution-based polarization splitter.
A mode-evolution-based polarization splitter suitable for high-index-contrast systems and directly integratable with a recently reported on-polarization rotator is described and its performance verified through both finite-difference time-domain and eigenmode expansion simulations. For a device length of 200 microm, greater than 22 dB of extinction is obtained across a 1.45-1.75-microm bandwidth.
متن کاملUltracompact and fabrication-tolerant integrated polarization splitter.
Design and fabrication of a 2×2 two-mode interference (TMI) coupler based on-chip polarization splitter is presented. By changing the angle between the access waveguides, one can tune the effective TMI length for the mode with less optical confinement (transverse magnetic, TM) to coincide with the target TMI length for a desired transmission of the mode with higher optical confinement (transver...
متن کاملA compact integrated polarization splitter/converter in InGaAsP/InP
A novel design for an integrated passive polarization splitter/converter combination is presented. The device consists of a Mach–Zehnder interferometer with polarization converters in both arms. The device is analyzed using the transfer matrix method and fabricated in InGaAsP–InP. Measurement results show a splitting ratio of approximately 10 dB and a conversion of>90%. This device can be monol...
