This tool can help you build boolean queries suitable for doing a broad search for different synonyms or spellings of each word. Start via the drop-down below or just start typing in the search field.
{{ row.typeTitle }}: ( )

Since our index often lack the full first name of people it can be difficult to correctly search by author.

Fill in the fields and let us help you build a good query:

If you need to find everything possible, consider only searching by last name.

Conference paper

Nonlinear Phase-Shift Cancellation in Dispersion-Shifted Fiber Transmission by All-Optical Back-Propagation

In Proceedings of 2020 Conference on Lasers and Electro-optics — 2020, pp. 1-2

We experimentally demonstrate an unrepeatered system with optical phase conjugation (OPC)-based receiver-side back-propagation. Dispersion-shifted fibers employed for transmission simplify the OPC symmetry requirements, leading up to 2.93-dB SNR gains for dual-polarization 16-QAM signals.
