Abstract
We report for the first time top emitting buried oxide vertical cavity lasers using transparent indium tin oxide electrodes, Our process ena bles broad-area VCSEL's to be fabricated in a single lithography step, thus allowing the fast turn-around time necessary for evaluating VCSE L epitaxial materials. The ITO contacts attain a peak transmission of 96%, a specific contact resistance of 10(-5) Omega . cm(2), and a shee t resistivity of 2.5x10(-4) Omega . cm. Under room temperature CW pump ing, the devices exhibit a minimum threshold current density of 1.2 kA /cm(2) at a wavelength of 801 nm, and have a maximum light output powe r of 5.2 mW.
