Curvilinear vector finite difference approach to the computation of waveguide modes

open access: yesAdvanced Electromagnetics, 2012
We describe here a Vector Finite Difference approach to the evaluation of waveguide eigenvalues and modes for rectangular, circular and elliptical waveguides. The FD is applied using a 2D cartesian, polar and elliptical grid in the waveguide section.

Comb‐Driven Coherent Optical Transmitter for Scalable DWDM Interconnects

open access: yesLaser &Photonics Reviews, EarlyView.
A comb‐driven coherent optical transmitter on a Si/SiN platform enables scalable DWDM interconnects by integrating ultra‐compact microring‐assisted modulators and interleavers. High‐baud coherent signaling achieves 400 Gb/s per wavelength and >$>$1 Tb/s multi‐channel transmission, with projected >$>$10 Tb/s per fiber, offering a path toward energy ...

A new configuration of dual mode rectangular waveguide filters [PDF]

open access: yes, 1995
A design technique for a new configuration of dual-mode waveguide filters based on a distributed parameter model is presented. The key point of the new configuration is that the coupling between the two diagonal modes in a square waveguide resonator is ...

How interference between the North Atlantic Oscillation and the tropical Indo‐Pacific convection modulates wave trains along the subtropical jet: Impacts on the Asian winter climate

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
This study reveals that the combined effects of the North Atlantic Oscillation (NAO) and anomalous Indo‐Pacific Walker circulation on the excitation of the wave train along the wintertime subtropical jet strongly depend on their phase combination. Their impacts interfere constructively or destructively over South Asia, leading to notable differences in
