Etching holes in vertical-cavity surface-emitting lasers creates better beam By Jim Kloeppel, U of I News Bureau University of Illinois researchers have found a way to significantly improve the performance of vertical-cavity surface- emitting lasers (VCSELs) by drilling holes in their surfaces. Faster and cheaper long-haul optical communication sys- tems, as well as photonic integrated circuits, could be the result. Low-cost VCSELs are currently used in those data communication applications where beam quality is of little impor- tance. To operate at higher speeds and over longer distances, new devices must function in a single transverse mode with a carefully controlled beam. “These characteristics are normally found only in very expensive lasers, not in mass-produced VCSELs,” said ECE Photo by Bill Wiegand Bill by Photo Professor Kent Choquette, a researcher ECE Professor Kent D.

United States knew that the LPD with its simple design, economy of materials, and broadband operation, was ideally suited for color television reception. The University of Illinois licked its chops at the thought of big royalties from the LPD and related patents. That those royalties never mate- rialized is not the fault of the Illinois antenna technology. Indeed, antenna engineers still recognize the LPD as one of the major design advances since Hertz’s simple dipoles and loops in the 1880s. And the LPD is only the most salient of several innovative broadband antennas to come out of ECE’s Antenna Laboratory between the end of World War II and 1971, when it was renamed the Electromagnetics Lab. What happened was that the An- tenna Lab established not only many venerable precedents in the world of an- tennas, but also one unlucky precedent in the world of patent law, thanks to a

These infringements not only cut into potential royalties for the university, but also reduced the value to JFD of the Illinois license; therefore, the contract between UIF and JFD required the uni- versity to defend its patents against in- fringers. UIF’s attorneys, Merriam Smith & Marshall of Chicago (Scarpelli’s firm), decided to focus on the Isbell LPD pat- ent because it was fundamental to the Mayes-Carrel resonant-V. All the cases except Winegard (which had no place of business in Illinois) were filed in the Northern District of Illinois in Chicago.

er-Tongue doctrine UIF’s attorneys were optimistic given the patent litigation procedures that oper- ated in 1970, when the Supreme Court agreed to resolve the conflict of circuits. Under the precedent of Triplett v. Lowe, established by the Supreme Court in 1936, the Seventh Circuit’s opinion in the Winegard case carried no special weight by virtue of its being handed down 16 months earlier than the Eighth Circuit opinion in Blonder-Tongue. Triplett v. Lowe established that even if a court had ruled in favor of one defendant, the pat- ent holder could sue other defendants for infringement of the same patent. Nei- ther UIF nor Blonder-Tongue questioned this precedent going into the Supreme Court trial in January 1971. But the Court under Chief Justice Warren Burger was Dwight Isbell (left) and Paul Mayes discuss the feed point of a planar, log-periodic, triangular toothed seeking to break the logjam of patent array (c. 1957). cases in the lower courts, and it asked the attorneys on both sides to brief the independence do not predict successful had left Illinois for Collins Radio and was court on Triplett v.
