Bent Solenoids with Superimposed Dipole Fields
Not Available We propose to design, demonstrate and develop highly stable, single-mode vertical cavity surface emitting lasers (VCSELs) in 1 x N arrays (N > 8) operating at 1.3 ¿m at 1GHz bandwidths. Sensors Unlimited will use a novel design based upon flip-bonding, substrate removal and dielectric stacks for both VCSEL mirrors. We will deliver individual VCSELs operating in a single mode at a 1.3 ¿m-wavelength capable of 1GHz bandwidth operation at the end of Phase I. This will include complete characterization of the device including operating wavelength, threshold current, output power, far-field pattern, thermal and current tuning of the lasers as well as bandwidth characterization. The dependence of laser threshold upon the nature of the Distributed Bragg Reflector (DBR) mirrors will also be studied. In Phase II, we will complete the optimization of the device in terms of the lasing threshold and wall-plug efficiency. We will also fabricate and deliver a 1 x 8 array of VCSELs. Prof. S. R. Forrest (Princeton University) and Milind Gokhale (Princeton University) will consult on this project.
