    Abstract: A tunable surface emitting laser includes on a semiconductor substrate (1) a first reflecting mirror (2); an active layer (4) on the first reflecting mirror which may be a DBR; a current confinement layer (6) resulting from partial oxidation of an AlGaAs layer; a conductive layer (7) on the current confinement layer (6) for providing a bias current to the active region; support portions (8) made from electrically insulating material like undoped GaAs; and a conductive film (9) which is provided above the conductive layer via a support portion (8) and which comprises a second reflecting mirror (11) like a HCG. A gap portion (14) is formed between the conductive layer (7) and the conductive film (9). The conductive layer (7) includes a high resistivity region (13) provided between the support portion (8) and the central current guiding region of the current confinement layer (6). Breakdown voltage of the tuning part is increased and rapid wavelength tuning via corresponding currents provided to the electrodes (12) is enabled allowing for faster movement of the second reflector (11).

    Abstract: A vertical cavity having a tunnel junction surface emitting laser (VCSEL) for emitting long wavelength light (i.e., 1200 to 1800 nanometers, though it is contemplated that the structures and techniques are applicable to other wavelength VCSELs). The tunnel junction may be isolated with an implant down into the top mirror through the tunnel junction and p-layer and a trench around the VCSEL down to at least past the tunnel junction. The trench may result in reduced capacitance and D.C. isolation of the tunnel junction. The implant is performed after the trench is made. Some of the implant may enter the bottom of the trench into the bottom mirror for some further isolation for the tunnel junction of the VCSEL. Further isolation and some current confinement may be provided with lateral oxidation of a layer below the tunnel junction. Internal trenches may be made from the top of the VCSEL vertically down to the oxidizable layer below the tunneljunction. Oxidation of that layer via these trenches may provide further isolation of the tunnel junction. Also, a bonding pad connected to a contact on the VCSEL with a bridge may have an open trench about their periphery for their isolation. Internal trenches may be placed on the pad and its bridge that go down vertically to the oxidizable layer. Oxidation via these trenches may provide further isolation for the pad and bridge if the latter is present.

    Abstract: A vertical cavity surface emitting laser [100] with a current guide comprised of an ion (160) implant region and an oxide structure (140). The oxide structure (140) is beneficially formed first, then, a gain guide ion implant region (160) is formed in or below the oxide structure (140). The ion (160) implant region extends into an active region (22). The energy and dosage used when forming the ion (160) implant gain guide can be selected to control the lateral sheet resistance and the active region's (22) non-radiative recombination centers.
