We will address the requirement for fault identification and isolation in fiber optic data links by incorporating an optical time domain reflectance (OTDR) functionality into the transceiver module. Our approach is to monolithically integrate a high speed photodetector that will sense reflections… More

This project will investigate the high speed modulation properties of monolithically integrated coupled-cavity VCSEL arrays with the aim of developing manufacturable, very high speed (>20GHz) directly modulated integrated laser arrays which have very low power dissipation (

This Small Business Innovation Research Phase I project will evaluate the feasibility of significantly improving the output power, temperature range of operation, and reliability of red VCSELs. The objective of the Phase I project is to develop a design approach for 650-680nm VCSELs that will… More

The objective of this Small Business Innovation Research Phase I project is to develop an integrated optical and electrical packaging technique that allows for the precision placement of high density, large arrays of VCSELs, LEDs, or photodetectors coupled with arrays of microlenses. The computed… More

This Small Business Innovation Research (SBIR) Phase II project will demonstrate significantly improved output power, temperature range of operation, and reliability of red VCSELs. Commercialization of red VCSEL technology has been plagued by the limited temperature range and output power of the… More

This Small Business Innovation Research Phase I project proposes to demonstrate a Composite Resonator VCSEL (CRVCL) which will achieve a 40-100Gbps data transmission rate. For more than a decade VCSELs have been the engine driving bandwidth increases at shorter distances (<300 meters) between… More

DESCRIPTION (provided by applicant): This project will develop a swept near-infrared light source that enables a portable hyperspectral tomographic functional optical imager. While such a device has many applications within endogenous NIR spectroscopy andimaging, or molecular imaging spectroscopy,… More

DESCRIPTION (provided by applicant): Infrared neural stimulation (INS) is a novel technology that holds promise for increasing the number of independent channels in neuroprostheses. A complementary technology to electrical stimulation (ES), INS has been used in the cochlea, vestibular system,… More
