TL;DR: In this article, a novel integrated polarization converter based on ultra short bends is presented, which has a potential for low loss and small device size, and a conversion value of 85% was experimentally measured with excess loss of 2.7 dB and overall dimensions of 975/spl times/83 /spl mu/m.
Journal ArticleDOI
Low-loss, compact, and polarization independent PHASAR demultiplexer fabricated by using a double-etch process
TL;DR: In this paper, a low-loss polarization independent 8 /spl times/8 PHASAR demultiplexer is presented for integration with electro-optical switches for application in integrated optical crossconnects, add-drop multiplexers and multiwavelength lasers.
Journal ArticleDOI
A compact integrated InP-based single-phasar optical crossconnect
C.G.P. Herben,Cgm Vreeburg,D.H.P. Maat,Xaveer Leijtens,Ys Oei,FH Groen,J.W. Pedersen,Piet Demeester,MK Meint Smit +8 more
TL;DR: The first integrated InP-based polarization independent optical crossconnect was reported in this paper, which can crossconnect signals at four wavelengths independently from two input fibers to two output fibers.
Journal ArticleDOI
A short polarization splitter without metal overlays on InGaAsP-InP
TL;DR: In this article, a very short polarization splitter on InGaAsP-InP was designed and realized for the first time, which used the large waveguide birefringence of the first-order TE and TM modes to obtain polarization selective directional coupling.
Journal ArticleDOI
A low-loss 16-channel polarization dispersion-compensated PHASAR demultiplexer
Cgm Vreeburg,C.G.P. Herben,Xaveer Leijtens,MK Meint Smit,FH Groen,J.J.G.M. van der Tol,P. Demcester +6 more
TL;DR: In this article, an improved technology for realizing high-quality PHASARs is reported, which is compatible with the integration of electrooptical switches for use in add-drop multiplexers.
