NanoOpto adds $4 million to first round

Optical components maker NanoOpto said Tuesday that it has raised an additional $4 million for its first round of funding, which brings its total financing to $20 million. The cash infusion came from new investor Draper Fisher Jurvetson and from previous investors such as Bessemer Venture Partners, Morgenthaler Ventures, New Enterprise Associates and U.S. Trust's Excelsior Venture Partners III. The company, which raised $16 million for the first round in December, makes chips for telecom equipment that power networks run by carriers. NanoOpto started initial production in its Somerset, N.J., chip plant in March and will reach volume production in mid-2002.
