The generation of midinfrared pulses through the optical rectification extended the radiation frequency from a few THz to several tens of THz. The coherent measurement of a detection frequency greater than 5 THz was demonstrated using a GaP and a ZnTe electro-optic sensor. This optoelectronic technique opens the door to the midinfrared ~midIR! region for coherent emission spectroscopy, time-dom...

Background: Pigment epithelium-derived factor (PEDF) is regarded as a multifunctional protein possessing neurotrophic and neuroprotective properties. PEDF has a very short half-life, and it would require multiple injections to maintain a therapeutically relevant level without a delivery system. However, multiple injections are prone to cause local damage or infection. To overcome this, we chose...

We demonstrate electrically pumped, heterogeneously integrated lasers on thin-film lithium niobate, featuring electro-optic wavelength tunability.

There is a relentless push for cost and size reduction in optical transmitters and receivers for fiber-optic links. Monolithically integrated optical chips in InP and Si may be a way to leap ahead of this trend. We discuss uses of integration technology to accomplish various telecommunications functions. key words: advanced modulation formats, coherent, fiber optic communication, gratings, indi...

Integrated-optic, astronomical, two-beam and three-beam, interferometric combiners have been designed and fabricated for operation in the L band (3 microm--4 microm) for the first time. The devices have been realized in titanium-indiffused, x-cut lithium niobate substrates, and on-chip electro-optic fringe scanning has been demonstrated. White light fringes were produced in the laboratory using...

glaucoma is a major cause of worldwide irreversible blindness. the central role of raised intraocular pressure (iop) is being questioned as many patients continue to demonstrate a clinically downhill course despite initial control of iop. the latest concept of recognizing glaucoma as a multifactorial, progressive, neurodegenerative disease of retinal ganglion cells (rgcss) associated with chara...

Ultra high bandwidth properties of fiber-optic signal processing systems could provide the necessary processing power for computationally demanding two-dimensional signal processing applications. The techniques of fiber-optic signal processing so far have not been applied to the area of two-dimensional signal processing. Further the matured fields of integrated optics and integrated photonics a...
