Reciprocity-induced symmetry in the round-trip transmission through complex systems
Szu-Yu Lee, Vicente J. Parot, Brett E. Bouma +1
Reciprocity is a fundamental principle of wave physics and directly relates to the symmetry in the transmission through a system when interchanging the input and output. The cohere…
Highly-stable, multi-megahertz circular-ranging optical coherence tomography at 1.3 um
Norman Lippok, Brett E. Bouma, Benjamin J. Vakoc
In Fourier-domain optical coherence tomography (OCT), the finite bandwidth of the acquisition electronics constrains the depth range and speed of the system. Circular-ranging (CR)…
Polarization constraints in reciprocal unitary backscattering
Qiaozhou Xiong, Nanshuo Wang, Xinyu Liu +5
We observed that the polarization state of light after round-trip propagation through a birefringent medium frequently aligns with the employed input polarization state "mirrored"…
Extended coherence length and depth ranging using a Fourier domain mode-locked frequency comb and circular interferometric ranging
Norman Lippok, Meena Siddiqui, Benjamin J. Vakoc +1
Fourier domain mode-locking (FDML) has been a popular laser design for high speed optical frequency domain imaging (OFDI) but achieving long coherence lengths, and therefore imagin…
