Since the inception of solid state semiconductors and device fabrication techniques, continuous scaling has been implemented as a key driver behind realizing faster electronics while optimizing for power consumption, improving the field in an exponential fashion (i.e. Moore’s Law) and facilitating modern technological advances that otherwise would have been impossible. In recent years, transistor gate length...

BPN703: High-Speed nanoLED with Antenna Enhanced Light Emission

Traditional semiconductor light emitting diodes (LEDs) have low modulation speed because of long spontaneous emission lifetime. Spontaneous emission in semiconductors (and indeed most light emitters) is an inherently slow process owing to the size mismatch between the dipole length of the optical dipole oscillators responsible for light emission and the wavelength of the emitted light. More simply stated: semiconductors behave as a poor antenna for its own light emission. By coupling a semiconductor at the nanoscale to an external antenna, the spontaneous emission rate can be...

The superiority of lidar compared to radio-frequency and ultrasonic solutions in terms of depth and lateral resolution has been known for decades. In recent years, both application pull such as 3D vision for robotics, rapid prototyping, self-driving cars, and medical diagnostics, as well as technology developments such as integrated optics and tunable lasers have resulted in new activities. Pulsed, amplitude-modulated continuous-wave (AMCW), and frequency-modulated continuous-wave (FMCW) lidars can all be used for ranging. The latter option enables excellent depth resolution at the...

BPN472: Nanoplasmonic Light Emitting Devices for Ultra-Fast Modulation

Erwin K. Lau
2010

Semiconductor nanocavities are of interest for their potential as threshold-less lasers and high-speed modulated sources. When cavity volumes are shrunk below the size of a cubic wavelength, the rate of spontaneous emission can be enhanced. This so-called Purcell enhancement has lead to the misconception that the modulation speed of nanocavity lasers can be significantly enhanced beyond that of their classical (large volume) counterparts. Here, by performing a detailed analysis, we show that the modulation bandwidth can, indeed, be increased by the Purcell effect, but that this...

MCW3: MEMS-Actuated Tunable Optical Microdisk Resonators

Ming Chang M Lee
2005

Semiconductor optical microdisk resonators are bulding blocks for most wavelength-division-multiplexing (WDM) photonic integrated circuits, including wavelength filters and add-drop multiplexers, optical delay lines, and group velocity dispersion compensators. Adding a tuning mechanism is desired to implement a dynamically reconfigurable function. The goal of this project is to make a high quality factor (Q), tunable, integrated microidk resoantor.
