  • Patent number: 7807489
    Abstract: A light-emitting device with a protection layer for Zn inter-diffusion and a process to form the device are described. The device of the invention provides an active layer containing aluminum (Al) as a group III element, typically AlGaInAs, and protection layers containing silicon (Si) to prevent the inter-diffusion of zing (Zn) atoms contained in p-type layers surrounding the active layer. One of protection layers is put between the active layer and the p-type cladding layer, while, the other of protection layers is disposed between the active layer and the p-type burying layer.

  • Patent number: 7608138
    Abstract: Provided is an apparatus 1 for measuring pressure loss in a filter 2, which apparatus includes filter holding means 3; fluid passing means; flow rate measuring means; pressure loss measuring means; and a flow path 6 which connects the four means such that a fluid can pass between the means. The apparatus further includes flow rate regulating means having a mainstream path 7; a tributary path 8 which is branched from the mainstream path 7 and communicates with the outside; and one or more flow path opening/closing members 9 capable of, in conjunction with the level of the fluid flow rate as measured through the flow rate measuring means, opening or closing the mainstream path 7 or the tributary path 8 such that the flow path opening ratio of each of the paths varies continuously or intermittently. The apparatus achieves reliable and convenient measurement of pressure loss with the flow rate of the fluid which passes through the filter 2 being maintained at a constant level by the flow rate regulating means.

  • Patent number: 7330495
    Abstract: The present invention is to provide a vertical cavity surface emitting laser diode (VCSEL) that has a functional distributed Bragg reflector (DBR) comprised of less number of pairs of reflective layers. The VCSEL of the invention include a lower DBR, an upper DBR and an active layer arranged between the upper and lower DBRs. The upper DBR is comprised of a plurality of pairs including GaAs layers and aluminum oxide layers, thus the GaAs layers and the aluminum oxide layers are alternately stacked to each other. Since the refractive index of the aluminum oxide (Al2O3) is 1.67 at 1.3 ?m and that of the GaAs is 3.51, the difference of these refractive index becomes 1.85, which is far greater than the combination of the AlAs and the GaAs, thereby decreasing the number of pairs for the DBR.
