Abstract: An optical apparatus is provided for an optical transceiver. The optical apparatus includes an interposer, a glass lens chip bonded to the interposer, and a plurality of bottom-emitting vertical-cavity surface-emitting lasers (VCSELs) flip chipped to the interposer. Each of the bottom-emitting VCSELs is fabricated on a respective substrate, at least one bottom-emitting VCSEL is capable of emitting an optical signal having a wavelength of about 850 nm, and at least a portion of the respective substrate on which the at least one bottom-emitting VCSEL is fabricated is removed to permit the at least one bottom-emitting VCSEL to emit the optical signal having the wavelength of about 850 nm to the glass lens chip.

Abstract: An example device in accordance with an aspect of the present disclosure includes a slab to transmit light, and a plurality of lenses and filters disposed on first and second surfaces of the slab. The lenses include an anti-reflective coating on at least one of the plurality of lenses at an end of the slab to couple light through the anti-reflective coating, and a reflective coating disposed on remaining ones of the plurality of lenses to cause the lenses to reflect light. The filters are offset from the lenses to form an optical zig-zag.

Abstract: A device can include an active optical device (AOD) to at least one of transmit and receive optical signals. The device can also include an interposer having the AOD mounted thereon. The interposer can be in thermal contact with a heat sink and the interposer is mounted on a substrate. The interposer can be formed of a thermally conductive and electrically insulating material. The interposer can include a via to electrically couple the AOD to another electrical device.
