Broadband Tuning (170nm) of InGaAs Quantum Well Lasers [PDF]
, 1990 The wavelength tuning properties of strained InGaAs quantum well lasers using an external grating for feedback is reported. Tunable laser oscillation has been observed over a range of 170 nm, between 840 and 1010 nm, under pulsed current excitation.

Simultaneous Detection of Longitudinal and Transverse Bunch Signals at a Storage Ring [PDF]
, 2018 To understand and control the dynamics in the longitudinal phase space, time-resolved measurements of different bunch parameters are required. For a reconstruction of this phase space, the detector systems have to be synchronized. This reconstruction can

Diced and grounded broadband bow-tie antenna with tuning stub for resonant tunnelling diode terahertz oscillators [PDF]
, 2016 Radiation from antennas integrated with indium phosphide (InP)-based resonant tunnelling diode (RTD) oscillators is mainly through the substrate because of the effects of the large dielectric constant.

Atom in a coherently controlled squeezed vacuum [PDF]
, 2006 A broadband squeezed vacuum photon field is characterized by a complex squeezing function. We show that by controlling the wavelength dependence of its phase it is possible to change the dynamics of the atomic polarization interacting with the squeezed ...
