摘要： An optical multimode fiber including a graded index core and an extended gradient core which has a negative refractive index difference with respect to the cladding. The fiber improves the bandwidth, reliability and complexity of the telecommunication systems that are based on multimode fibers. The fiber reduces the differential mode delay among modes. The fiber thereby allows achieving large bandwidth even in the case when the highest order modes are excited. This has positive effects to the conditions that need to be fulfilled by the components such as optical sources, connectors, fiber couplers, other optical components, cables, etc. The fiber eliminates negative impact of the cladding that allows for reduction of fiber core size and the difference between the cladding and the core and thereby allows for achieving the larger bandwidth of optical fiber at lower fiber production cost.

摘要： Opto-electronic signal processing systems, apparatus and methods to extract a measured parameter from one or more interrogated optical sensors are disclosed. The apparatus includes an integrated laser module, an electronic control and processing unit, an optical coupling element, and one or more light receivers. Light is reflected back from the optical sensor through the optical coupling element to the light receiver(s).

According to the method, a wavelength sweep from the integrated laser module wavelength is swept, simultaneously measured and stored in memory of the electronic control and processing unit. The optical sensor response is recorded during the sweep and combined with stored emitted wavelengths to obtain spectral characteristics of interrogated optical sensor.

摘要： Variants of a method for manufacturing a microlens of any desired shape at the extremity of a lead waveguide are provided. A lens element having a non-uniform radial etchability profile is provided at the extremity of the lead waveguide. Preferably, the etchability profile is determined by a non-uniform radial distribution of dopants in the lens element. A spacer may optionally be placed between the waveguide and the lens element. The lens element is then brought down to an appropriate length and etched to its final shape which is mainly determined by the dopant distribution. An optical coupling assembly having a non-uniform radial distribution of dopants therein is also provided.

摘要： A bend-loss tolerant multimode fiber transmission system is provided. The system includes: a transmission fiber having a core and a cladding, and a mode-launching system for selectively exciting only a useful portion of the transmission modes, that portion corresponding to high effective refractive indices relative to a refractive index of the cladding the useful portion corresponding to a substantial number of modes. The mode-launching system may include a lead-in fiber, coupled to the transmission fiber, supporting a number of lead-in modes substantially corresponding to the number of transmission modes in the useful portion. The transmission fiber may have a refractive index profile, within a region of its core that is aligned with the lead-in fiber core, which has a shape that matches a refractive index profile shape in the lead-in fiber core. The transmission fiber core may have a graded refractive index profile that is parabolic or nearly parabolic or truncated.
