Electrical time-domain measurements and transmission response measurements were made using a 31-cm-long YBaCuO superconducting thin-film microstrip line and a YBaCuO ground plane, each on separate 1-cm LaGaO/sub 3/ substrates, with a 125- mu m sapphi

The critical current density ${J}_{c}$(B,T) is measured to 15 T for c-axis-perpendicular expitaxial thin films of ${\mathrm{YBa}}_{2}$${\mathrm{Cu}}_{3}$${\mathrm{O}}_{7}$ with ${J}_{c}$(0,77 K) of order ${10}^{6}$ A/${\mathrm{cm}}^{2}$. Even in the

Electrical time domain measurements and transmission response measurements were made using a 31‐cm‐long, YBaCuO superconducting thin‐film microstrip line and a YBaCuO ground plane, each on separate 1‐cm LaGaO3 substrates, with a 125‐μm sap

From picosecond pump‐probe and forward degenerate four‐wave mixing (DFWM) experiments, we obtain the near‐band‐gap nonlinear absorption and refraction properties of GaInAsP for λ∼1.5 μm. Using a mode‐locked color center laser, the nonli

Laser action has been achieved in 13 gases at high pressures using pulsed transverse excitation. A total of 149 wavelengths from 0.8 to 28μ was observed. Pulse lengths were found to lie in the range 0.2–5μsec. Several gases operate at atmospheric

The rapid degradation rate generally observed in InP/InGaAsP mushroom stripe lasers can be considerably decreased by regrowing the open sidewalls of the active stripe with low‐doped InP in a second epitaxial step using the hydride vapor phase trans

We have measured sheet resistance and mobility changes for a series of In0.53Ga0.47As layers as a result of hydrogen, boron, and beryllium implantation. We find that boron and beryllium implantation can produce a two order‐of‐magnitude increase i

GaInAsP/InP double heterostructures grown by chemical‐beam epitaxy have been used in conjunction with liquid‐phase‐epitaxial regrowth to fabricate high‐performance buried heterostructure lasers operating at a wavelength of 1.5 μm. These lase
