At the 2024 CS MANTECH conference, Kevin presents his work on using anti-phase coatings to achieve high-power, single-mode, single-polarization performance in VCSELs.

At the 2024 CS MANTECH conference, Robert presents his work finding unique device physics in his transistor injected quantum cascade structure (TI-QCS).

At the 2023 CS MANTECH conference, Kevin presents his work on using anti-phase coatings to achieve high-power, single-mode performance in VCSELs.

At the 2023 CS International Conference in Brussels, Belgium, Leah gave an invited talk on her work making heterogeneously integrated VCSELs on silicon. These VCSELs integrated via epitaxial transfer have improved thermal performances compared to non-integrated counterparts.

The group attended the “Celebrating the Life of Professor Emeritus Nick Holonyak Jr.” service in honor of Dr. Holonyak’s passing. Dr. John Dallesasse spoke as a past student of Holonyak, and Leah Espenhahn spoke as a current student of Dallesasse and thus a “research grandchild” of Holonyak.

After a number of speeches in honor of Dr. Holonyak, red LEDs in heart casings were past out to attendees in honor of Holonyak, who created the first visible LED. The group honors the passing of a great man, and give their best wishes to his widowed wife, Kay.
