Signal modulation and relative intensity noise properties of transistor laser and nano-cavity VCSEL
… the vertical cavity transistor laser (VCTL) can in principle provide better performance than the edge-emitting TL. We have demonstrated the selective oxide-confined VCTL operated at -80 oC. To improve the performance of the VCTL device, we studied the optical modal dimension effect on …

Development of vertical cavity transistor laser and microcavity laser
… the first vertical cavity transistor laser (VCTL) operation. Due to the dynamic charge transport in the active region, the transistor laser can achieve shorter carrier lifetime (~ 29 ps), making it especially suitable for high-speed lasers. We discuss the VCTL material and layout design, …

Development of high speed vertical cavity surface-emitting semiconductor diode laser and transistor laser
… oxide-confined vertical cavity transistor laser (VCTL) is realized with a trench oxidation process and a lateral-feeding base metal design. To further reduce the excessive emitter series resistance, a VCTL with AlGaAs and dielectric distributed Bragg reflector (DBR) is fabricated. Because of the …

Microwave characterization of vertical cavity surface emitting diode laser and transistor laser
… oxide-confined vertical cavity transistor laser (VCTL) is realized with a trench oxidation process and a lateral-feeding base metal design. To further reduce the excessive emitter series resistance, a VCTL with partially etched mesa is developed and fabricated. The tunneling modulation aspect and …

Development of high-speed vertical-cavity surface-emitting diode laser and vertical-cavity transistor laser for shortreach optical interconnects
… of a vertical-cavity transistor laser (VCTL) is presented. The high threshold current issue present in previous devices is identified and attributed to the low-Q cavity formed below the emitter contact. We present the modified layout and process flows of VCTL to resolve the trench …
