    摘要： An optical assembly (10) includes an optical subassembly (40) containing a prefabricated long wavelength laser (30) optically coupled to a prefabricated short wavelength laser (20) located in a housing (18). The optical subassembly (40) may be removably installed in the housing (18) in which the short wavelength laser (20) is contained. The short wavelength laser (20) optically pumps the long wavelength laser (30) resulting in a long wavelength laser output (17). The optical subassembly (40) allows the independent fabrication, optimization and testing of the short wavelength laser (20) and the long wavelength laser (30).

    摘要： An optically pumped vertical-cavity surface-emitting laser (VCSEL) device (66) and a method of fabricating the device utilize two separate substrates (70 and 74) that perform a filtering operation to selectively transmit only light having a long peak wavelength that is generated by the device. The optically pumped VCSEL device is a self-pumped device that can generate the pump light (76) to drive the device to emit output laser (78) light having a long peak wavelength. Preferably, the output laser light has a peak wavelength between 1250 nm and 1700 nm, which is desirable for applications in the field of optical communications. The optically pumped VCSEL device includes a short-wavelength VCSEL (68) formed on one (70) of the two substrates and a long-wavelength VCSEL (72) formed on the other substrate (74). The short-wavelength VCSEL is a current-driven VCSEL that generates short-wavelength light to drive (i.e., optically pump) the long-wavelength VCSEL. The short-wavelength VCSEL and the long-wavelength VCSEL are bonded together such that the two substrates are separated by the two VCSELs. A transparent optical adhesive material or a metallic bonding material (88) may be utilized to bond the short-wavelength VCSEL onto the long-wavelength VCSEL. Preferably, flip-chip technology is used for the bonding step. The substrates are wavelength-selective with respect to propagating light, so that short-wavelength light generated by the short-wavelength VCSEL and not absorbed by the long-wavelength VCSEL is mostly absorbed by the two separate substrates. However, the long-wavelength light generated by the long-wavelength VCSEL is allowed to be transmitted through the substrates as output laser light.

    摘要： An optically pumped vertical-cavity surface-emitting laser (VCSEL) device (66) and a method of fabricating the device utilize two separate substrates (70 and 74) that perform a filtering operation to selectively transmit only light having a long peak wavelength that is generated by the device. The optically pumped VCSEL device is a self-pumped device that can generate the pump light (76) to drive the device to emit output laser (78) light having a long peak wavelength. Preferably, the output laser light has a peak wavelength between 1250 nm and 1700 nm, which is desirable for applications in the field of optical communications. The optically pumped VCSEL device includes a short-wavelength VCSEL (68) formed on one (70) of the two substrates and a long-wavelength VCSEL (72) formed on the other substrate (74). The short-wavelength VCSEL is a current-driven VCSEL that generates short-wavelength light to drive (i.e., optically pump) the long-wavelength VCSEL. The short-wavelength VCSEL and the long-wavelength VCSEL are bonded together such that the two substrates are separated by the two VCSELs. A transparent optical adhesive material or a metallic bonding material (88) may be utilized to bond the short-wavelength VCSEL onto the long-wavelength VCSEL. Preferably, flip-chip technology is used for the bonding step. The substrates are wavelength-selective with respect to propagating light, so that short-wavelength light generated by the short-wavelength VCSEL and not absorbed by the long-wavelength VCSEL is mostly absorbed by the two separate substrates. However, the long-wavelength light generated by the long-wavelength VCSEL is allowed to be transmitted through the substrates as output laser light.
