TuH1.1 - BROADBAND AND LOW-LOSS SILICON-PHOTONIC PASSIVES: LEVERAGING BIREFRINGENCE OF SILICON CHANNEL WAVEGUIDE FOR COHERENT APPLICATIONS
Abstract
Abstract
Silicon photonic(SiPh) passives that can be fabricated with high-yield and provide low-loss and wide-bandwidth operation are key enablers for SiPh applications in coherent optical communication systems. Here, we discuss high-performance inter-polarization mixers, power splitters/combiners, polarization manipulators, fiber-to-chip couplers allowing for novel SiPh coherent receiver designs.
TuH1.2 - HIGHLY DISPERSIVE COUPLED MODES IN A SIN/SIO2/SI HETEROSTRUCTURE
Abstract
Abstract
We present a SiN/SiO2/Si heterostructure that can achieve extremely high dispersions (|Dλ|>107 ps/nm/km). The large group velocity difference between the SiN and Si waveguides results in such high dispersions.
TuH1.3 - BROADBAND SILICON TM-PASS POLARIZER USING A SLOT-ASSISTED PERIODIC WAVEGUIDE
Abstract
Abstract
We demonstrate a compact (21 x 0.5 μm2) silicon TM-pass polarizer based on a slot-assisted periodic waveguide. Measured results show low insertion loss for the TM mode (average 0.7dB) and high TE loss (average 41.3dB) over a 100 nm wavelength range, centered at 1.55 μm.

Abstract
Abstract
A 6-mode exchanger composed of cascaded long-period-grating waveguide is proposed for mode-division-multiplexing system. Theoretical design shows low-loss and highly efficient mode exchanging operation is possible. Total mode dependent loss of the system is reduced for multiple exchanging operations in few-mode-fiber transmission.
