A tunable laser transmitter configured in a small package subassembly coupled to a printed circuit board. The tunable laser transmitter includes a housing with a volume formed by exterior walls.
Methods, systems and devices for optical-signal-to-noise-ratio monitoring
A device for optical-signal-to-noise (osnr) monitoring can include: a delay-line interferometer configured to connect with a tunable optical filter; and two or more power detectors to measure outputs of the interferometer; wherein one or more parameters are optimized for different transmission baud rates to improve accuracy. In addition, a method can include: connecting an input of a delay-line interferometer with an output of a tunable optical filter, and an output of the delay-line interferometer with an input of a power detector, to form an optical-signal-to-noise (osnr) monitoring apparatus; optimizing one or more parameters of the osnr monitoring apparatus for different transmission baud rates to improve accuracy..

Supply modulation for radio frequency power amplification
The subject matter described herein relates to supply modulation for power amplification. In one embodiment, the voltage level of the envelope with a tunable threshold voltage.
Methods and systems for transport-of-intensity imaging
A transport-of-intensity imaging system is proposed which incorporates a control element positioned in an optical relay system, such as a 4f optical relay system, between a microscope system for generating an image of a specimen, and an image capturing device. The control element is located with an optical relay system, and is controllable to vary the focal plane without changing the spacing of the specimen and the image capturing device.

Low-temperature synthesis of colloidal nanocrystals
Low-temperature organometallic nucleation and crystallization-based synthesis methods for the fabrication of semiconductor and metal colloidal nanocrystals with narrow size distributions and tunable, size- and shape-dependent electronic and optical properties. Methods include (1) forming a reaction mixture in a reaction vessel under an inert atmosphere that includes at least one solvent, a cationic precursor, an anionic precursor, and at least a first surface stabilizing ligand while stirring at a temperature in a range from about 50° c.
