Chiral Photonics, Inc. demonstrates Pitch Reducing Optical Fiber Array (PROFA) enabling highly dense 2D fiber array interfaces inside Go!Foton booth

PINE BROOK, NJ, Feb. 15 - The PROFA product line is an evolution of Chiral Photonics’ successful Spot Size Converting Interconnects (SSCIs) that interface standard optical fibers with photonic integrated circuits (PICs). PROFA is a multichannel, two-dimensional dense fiber array best suited for vertical interfacing to, for example, VCSELs, receivers or vertically coupled gratings.

A monolithic glass structure incorporating an adiabatic taper and integrated pigtails brings multiple optical channels close together for efficient, space-saving coupling. The technology reduces channel pitch while tailoring numerical aperture (NA) of individual channels to meet customers’ needs. At OFC/NFOEC 2012 in Los Angeles, Chiral Photonics will display a 50+ channel device with singlemode waveguides in the visible spectral range with channel-spacing of less than 40 um. Traditional solutions for coupling photonic ICs utilize GRIN lens technology, lensed fibers with V-grooves or other solutions which rely on air gaps and more complex production alignment techniques.

These techniques are suitable for moderate channel densities but pose substantial thermal expansion/excursion and related reliability challenges. An additional limitation of a conventional, lens-based coupling technique is its inability to control channel spacing and NA independently. Chiral Photonics will display the PROFA at the exhibition floor’s entrance inside Go!Foton’s booth # 1603.
