A large variety of channel-dropping filters operate through the use of band-rejection filters, and since the microwave art is pushing the usable spectrum to higher and higher frequencies, low heat

We characterize the mode profiles, delays and mode-dependent gains of an erbium-doped step-index multimode fiber using C2 imaging based on a swept-wavelength interferometer.

We investigate the role of mode-dependent loss (MDL), gain (MDG), and noise figure (MDF) in optically amplified multiple-input-multiple-output space-division multiplexed (MIMO-SDM) communication sy

We report simultaneous transmission of 6 spatial and polarization modes, each carrying 40-Gb/s QPSK channels over 96 km of a low-DGD few-mode fiber.

We report simultaneous transmission of six spatial and polarization modes, each carrying 40 Gb/s quadrature-phase-shift-keyed channels over 96 km of a low-differential group delay few-mode fiber.

We report about mode-multiplexed transmission over few-mode fibers with 10 or more spatial modes. We also describe the latest progress in mode-multiplexers and optical amplifiers.

We experimentally demonstrate 8 dB of mode-equalized distributed Raman gain using a backward pumping scheme.

We experimentally demonstrate 8 dB of mode-equalized distributed Raman gain using a backward pumping scheme.

We demonstrate a three-dimensional adiabatically-tapered mode-selective spacedivision multiplexer fabricated by ultrafast laser inscription.

A diffraction-coupled laser array has been actively mode-locked in an external cavity to yield Gaussian pulses as short as 61 psec FWHM with a peak power of 1.1 W and an average power of 0.07W.
