摘要: Items of material are patterned on a substrate by forming a layer of photoresist on the substrate and a layer of metal on the photoresist. The photoresist is patterned to define an opening exposing a portion of the substrate and the metal is patterned to define an aperture smaller than the opening so as to divide the exposed surface of the substrate into shadow areas and a non-shadow area. A first material system is evaporated generally perpendicular to the aperture to form a first organic light emitting diode on the surface of the substrate in the non-shadow area and second and third material systems are evaporated at angles to the aperture to form second and third organic light emitting diodes in the shadow areas. Passivation material is evaporated perpendicularly onto the first diode and at the angle onto the second diode.

摘要: A sensor (10,30,40,50,70) for detecting chemicals and changes in the surrounding environment utilizes a sol-gel sensor element (14,16,17,54,56,57) containing a chemical indicator. Grooves (12,13,24,52,53) are formed in a substrate (11,51). The grooves are filled with a sol-gel material having a chemical indicator, and the sol-gel is cured to adhere to the substrate (11,51). The grooves (12,13,24,52,53) are formed to facilitate optically coupling a fiber optic cable (46) to the sol-gel sensor element. Light is coupled from the fiber optic cable (46) to the sol-gel sensor element (14,16,17,54,56,57).

摘要: A method of fabricating VCSELs including the steps of epitaxially growing a first mirror stack of a first conductivity type, an active region on the first mirror stack, and a first portion of a second mirror stack of a second conductivity type on the active region. A dielectric layer is then formed on the first portion of the second mirror stack, patterned to define an operating region and a remaining portion of the second mirror stack is epitaxially grown on the first portion to form a complete second mirror stack. Portions of the second mirror stack overlying the dielectric layer are polycrystalline in formation and substantially limit the remaining portion of the second mirror stack to the operating region. The polycrystalline layers can then be removed and electrical contacts formed.

摘要: A vertical cavity surface emitting laser (VCSEL) having sensing capabilities is fabricated by forming a layer having the capability to change the threshold current of the VCSEL. This can be accomplished by forming a deformable membrane or a cantilevered beam on the VCSEL. The deformation of movement of the beam causes a change in the threshold current of the VCSEL, so that it can go from lasing to nonlasing or vice versa. In addition, a layer which changes reflectivity in the presence of a particular chemical can also be formed on the VCSEL to produce the same result.

摘要: VCSELs including a central active layer with upper and lower mirror stacks wherein a circular trench is formed in one mirror stack to define a lasing area. The trench reduces reflectivity to prevent lasing outside the operating area and a deep beryllium implant in either of the mirror stacks, along with the trench, confines current distribution to maximize power output and efficiency. A transparent metal contact is used as a top contact in one embodiment.
