An insider's view on the merits of optical integration

One of the pleasures of attending the OFC show, held in Los Angeles last month, is the many conversations possible in one location. The downside is that too many are cut short due to the show's hectic schedule. One exception was a conversation with Valery Tolstikhin (pictured), held in a quiet room prior to the exhibition hall's opening.

Tolstikhin is president and CEO of Intengent, the Ottawa-based consultancy and custom design service provider, and an industry veteran of photonic integration. In 2005 he founded OneChip Photonics, a fabless maker of indium phosphide photonic integrated circuits for optical access

One important lesson he learned at OneChip was how the cost benefit of a photonic integrated circuit (PIC) can be eroded with a cheap optical sub-assembly made from discrete off-the-shelf components. When OneChip started, the selling price for GPON optics was around $100 a unit but this quickly came down to $6. "We needed sales in volumes and they never came close to meeting $6," says Tolstikhin.
