UDWDM-PON using low-cost coherent transceivers with limited tunability and heuristic DWA [PDF]
, 2016 A new Passive Optical Network (PON) for access, making use of Ultra Dense Wavelength Division Multiplexing (UDWDM) by densely spacing channels at few GHz, and introducing the “wavelength-to-the-user” concept, is proposed.

BCARS Simulated Phantom Dataset for Evaluation of Processing Pipelines
Journal of Raman Spectroscopy, Volume 57, Issue 3, Page 530-543, March 2026.A tissue phantom, containing fingerprint Raman spectra at each pixel, is developed to evaluate Raman signal processing pipelines. The phantom is created from a BCARS image of a murine hepatic tissue. ABSTRACT Broadband coherent anti‐Stokes Raman scattering (BCARS) microscopy is a powerful label‐free biological imaging technique, but the raw signal ...

Local sampling of the quantum phase-space distribution of a continuous-wave optical beam
New Journal of Physics, 2012 It is shown how the quantum phase-space distribution of a continuous-wave (cw) optical beam can be obtained independently at each point in phase space by a combination of unbalanced homodyne and balanced-heterodyne techniques.

Dispersion‐Less Dissipative Soliton Fiber Laser
Laser &Photonics Reviews, Volume 20, Issue 6, 18 March 2026.A dispersion‐less fiber laser architecture generates high‐energy, pedestal‐free picosecond pulses without resorting to conventional pulse stretching. This energy‐managed laser achieves remarkable flexibility in pulse parameters, delivering up to 0.54 μJ$\mathrm{\mu}\mathrm{J}$ pulses with minimal spectral distortion using standard telecom components ...

Photomixing for Coherent Retrieval of THz Waveforms from a Frequency Multiplier
EPJ Web of Conferences, 2013 THz waveforms generated with an electronic frequency multiplier are sampled with a heterodyne detection technique using a LTG-GaAs photomixer and the optical beat of two near-infrared lasers.

ESPERDYNE: A dual‐band heterodyne monitor and ultrasound recorder for bioacoustic field surveys
Methods in Ecology and Evolution, Volume 17, Issue 3, Page 768-777, March 2026.Abstract Background. Ultrasonic monitoring is essential for ecological studies of bats and other animals, yet high‐performance field devices remain prohibitively expensive and inaccessible—particularly in biodiversity‐rich regions with limited research infrastructure.
