On the heels of the elusive all-optical circuit By Anita S. Becker, Associate Editor, ICD Engineers and executives at Nanovation Technologies Inc. (Miami, FL) believe they've found the Holy Grail that will at last unleash the power of the all-optical network--the photonic circuit. They also believe the much-sought-after technology that would enable inexpensive, space-efficient, non-heat sensitive, all-photonic switching equipment for fiber-optic networks may be in the telecommunication industry's hands by next year. Earlier this year, the company, formerly known as U.S. Integrated Optics, announced expectations of launching its first product line of fully integrated optical components capable of delivering high-speed, high-capacity telecommunications services by year's end. Nanovation has since revised that expectation to beta testing in first quarter 2000, with general availability soon after. There has been some skepticism from within the industry that Nanovation's claims are too good to be true and will not imminently lead to the revolutionary transformation of the fiber network as promised. However, Nanovation has developed an all-photonic circuit that it says can be made to be 100 times smaller than a human hair and operate up to 1000 times faster than its conventional electronic and optoelectronic counterparts. Until September, no one other than selected customers had seen a demonstration of the company's integrated optical circuit, which comprises the company's patented photonic ring laser, photonic switch, and strongly confined waveguide. Nanovation quieted some of the naysayers with its first public demonstration of the technology at the recent National Fiber Optic Engineers Conference (NFOEC) held in Chicago. "The technology is there, and we have been talking to our customers about the technology [for some time]," says Michael Hassebrock, senior vice president of marketing for Nanovation. "[NFOEC] was kind of our debut. We had been written up in [various magazines and newspapers], but until now we really hadn't gone out in the industry and basically showed ourselves as a company publicly with our products and our prototypes." "To switch an optical signal today, you've got to take it from an optical state and convert it to an electrical state, do the switching, then reconfigure and reswitch that signal to the direction it needs to go and then put it back into the optical state and send it on its way," explains Hassebrock. Using Nanovation's technology, the process would be switched completely in the optical domain with no electronic conversions necessary. "We are professing that we have an all-optical approach to switch photons. That's the real difference between us and other companies, and that's where our strategic advantage is and it makes us unique in the marketplace.... We believe our technology will drive down the cost of the hardware associated with supporting fiber-optic networks. It will also allow fiber service to be pushed out further to the end user, to the home." Nanovation holds patents on various photonic technologies, including the microcavity laser, microcavity resonator, and waveguide trundling, as well as a number of related subpatents. The company's key technology, the elliptical optical resonator, is designed for switching photons. The first device of its kind, this microcavity resonator channels photons into paths, or waveguides, to harness their power for telecommunications applications. The resonator and its sister device, the microcavity laser, are the fundamental building blocks of what Nanovation calls Microcavity Technology (MCT).

The company also plans to deliver advanced photonic devices with the ability to integrate laser sources and optical switches on the same device. It will initially sell its components to telecommunications and data networking equipment manufacturers and to original equipment manufacturers that supply subsystems.
