17 G directly modulated datacom VCSELs

Johnson, Ralph H.; Serkland, Darwin K.

The next generation 850 nm datacom VCSEL to go into production will be the 17 G VCSEL. It is not certain that direct modulation will be suitable given the reliability, supply voltage, and temperature range required. This paper is a first look at VCSELs designed and targeted for production 17 G use. The design is discussed and LIV and small signal frequency response is presented. © 2008 Optical Society of America.
