DNA Self-Switchable Microlaser
ACS Nano, 2020Advances in switchable microlasers have emerged as a building block with immense potential in controlling light-matter interactions and integrated photonics. Compared to artificially designed interfaces, a stimuli-responsive biointerface enables a higher level of functionalities and versatile ways of tailoring optical responses at the nanoscale ...

Semiconductor Microlaser Linewidths
Physical Review Letters, 1994Semiconductor microdisk laser linewidths are measured for cavity volumes near a cubic wavelength. The linewidths remain near the subthreshold values for pump powers well above threshold in agreement with a microscopic theory that includes the coupled dynamics of the optical emission and the nonequilibrium electron-hole gas in the cavity.

Self‐Assembled Flexible Microlasers
Advanced Materials, 2012Hemispherical microresonators with tunable sizes are obtained based on the hydrophobic effect on distributed Bragg reflectors. Under optical excitation, whispering gallery mode lasing is observed from the dye-doped microresonators at room temperature. The results indicate the potential application of the flexible microresonators in photonic integrated ...

IEEE Journal of Quantum Electronics, 1991
A Cerenkov microlaser (CML) is proposed. The device uses an electron beam and a semiconducting-film-loaded open, quasi-optical resonator to produce coherent, electromagnetic radiation at submillimeter and far-infrared wavelengths. General expressions for the tuning, gain, and constraints due to beam quality are used, together with optical and material ...

Ultrafast control of vortex microlasers
Science, 2020Ultrafast vortex microlasers For applications in ultrafast communication, all-optical switches will require low energy consumption, high speed, a strong modulation ratio, a small footprint, and on-chip integration. Although the small footprint and on-chip integration are accessible, the trade-off between low energy consumption ...

Monolithic-integrated microlaser encoder
Applied Optics, 1999We have developed an extremely small integrated microencoder whose sides are less than 1 mm long. It is 1/100 the size of conventional encoders. This microencoder consists of a laser diode, monolithic photodiodes, and fluorinated polyimide waveguides with total internal reflection mirrors.
