12 May 2009 Supporting mode fields smaller than 2 microns, couple to waveguides, even sub-micron dimensioned, with demonstrated fiber-to-chip coupling losses of approximately 1.8 dB. Delivering Polarized light to 20 dB PER thru hole is now easier to realize as well as arrays with center to center spacing tighter than 20 microns. Chiral's Fiber SSC (C-FSSC) outperforms Lens Fiber (LF) and On Chip Spot Size Convertor (OC-SSC):
+ Less complex InP PIC
+ Support < 1 micron mode field
+ No air gap, > stable
+ Support for arrays, tighter spacing
+ Produced on automated process in USA location
+ bring light to hermetic pkg w/o affecting 20 dB PER
+ improve overall cost and alignment time
+ improve overall coupling stability over lens fiber
+ improve use of on chip PIC real estate, move SSC to fiber
+ more PICs per wafer by removal of on chip SSC
+ angle cuts enabling best interface to your facet OK!
+ Big improvement in Coupling Efficiencies!
+ Look Different at fiber! |
