Oblique Deposition of Ti/Pt/Au Electrode on Photonic Crystal for Vertical Current Injection

NTT develops current-injection photonic-crystal laser

NTT Laboratories have focused on finding a radical solution to the problem of high power consumption and heat generation in ICT equipment by reducing the power consumption of microprocessors (MPU). This is because MPUs consume most of the power in this equipment. In this context, NTT Laboratories have developed optical data transmission technologies for off-chip and on-chip optical interconnect...

Double Photonic Quasi-Crystal Structure Effect on GaN-Based Vertical-Injection Light- Emitting Diodes

Progress in Photonic Crystal Vertical Cavity Lasers

Recent progress and achievements in creating single fundamental mode vertical cavity lasers with the technique of etching a 2dimensional pattern of photonic crystal holes into the top distributed Bragg reflector are described. A simulation method for the design of single mode lasers is described, along with accuracy and limitations in predicting modal properties in these devices. Progress in im...

Single mode photonic crystal vertical cavity lasers

We report the accuracy of the photonic crystal model in describing the characteristics of vertical cavity surface-emitting lasers with lateral optical confinement consisting of a periodic array of etched circular holes. Experiments were carried out to compare predictions of the photonic crystal model to observed modal device characteristics, and the oxide aperture size was optimized to give max...
