Article Abstract
An ultra-compact and polarization-independent optical power splitter with a variable splitting ratio has been proposed based on the inverse design method. The footprint of the simulated device is only 1.96×1.96µ, demonstrating its highly compact nature. The simulation results exhibit that the transmission efficiencies of the device structures with ratios of 1:1, 1:1.5, and 1:2 exceed 92% for both TE and TM polarization states within a bandwidth wavelength of 50 nm (1525-1575 nm). The insertion losses are less than 0.38 dB. Additionally, the simulated device exhibits high fabrication tolerances.

Subwavelength structure engineering is employed to balance the coupling coefficients of TE and TM polarizations as well as a footprint reduction. The device possesses ultra-compact (1.

By using the subwavelength structure in the coupling region, the coupling strength is greatly enhanced only for TE polarization, so that the coupling strength could be equivalent between TE and TM polarizations. Both complete coupling and 3 dB splitting have been demonstrated.

Two devices, one for each polarization state, were designed, fabricated, and characterized. Both devices offer comparable or higher transmission efficiencies and extinction ratios, are easier to fabricate, exhibit larger bandwidths and are more tolerant to fabrication errors, when compared to alternatives.
View Article and Find Full Text PDFA polarization-independent 2 × 2 switch based on silicon-wire waveguides has been realized with a compact size of 600 × 500 μm². Polarization-independent operation was achieved with a polarization-diversity technique which implements polarization splitters, TE-TM intersections, and Mach-Zehnder switches. The extinction ratios of the 2 × 2 switch for TE, TM, and a mixed polarization at a wavelength of 1550 nm were measured to be larger than 30 dB, 25 dB, and 30 dB, respectively.
