NTT develops current-injection photonic-crystal laser
ثبت نشده
چکیده
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 interconnection in MPUs.

Sensitivity Enhancement of Ring Laser Gyroscope Using Dielectric-Graphene Photonic Crystal
In a ring laser gyroscope, due to the rotation and the Sagnac effect, a phase difference between the two counter-propagating beams is generated. In this device, the higher phase difference between these two beams causes the better the interference pattern detection, and thus the sensitivity is increased. In this paper, the effect of inserting a dielectric-graphene photonic crystal inside a ring...
متن کاملDesign of the [SiO2/ZrO2] photonic crystal filter for application in 350-nm laser safety glasses
In this paper, a one-dimensional photonic crystal filter based on the [SiO2/ZrO2] bilayer have been designed for application in safety glasses for working in 350-nm wavelength. High power lasers with low wavelength e.g. 350-nm have very high power which can cause serious damage to the operator’s eyes. In this paper using the transfer matrix method and theoretical calculation in MATLAB software ...
متن کاملGaN photonic-crystal surface-emitting laser at blue-violet wavelengths.
Shorter-wavelength surface-emitting laser sources are important for a variety of fields, including photonics, information processing, and biology. We report on the creation of a current-driven blue-violet photonic-crystal surface-emitting laser. We have developed a fabrication method, named "air holes retained over growth," in order to construct a two-dimensional gallium nitride (GaN)/air photo...

متن کاملQuantum cascade surface-emitting photonic crystal laser.
We combine photonic and electronic band structure engineering to create a surface-emitting quantum cascade microcavity laser. A high-index contrast two-dimensional photonic crystal is used to form a micro-resonator that simultaneously provides feedback for laser action and diffracts light vertically from the surface of the semiconductor surface. A top metallic contact allows electrical current ...
