Spiral Transformation for High-Resolution and Efficient Sorting of Optical Vortex Modes
Yuanhui Wen, Ioannis Chremmos, Yujie Chen +3
Mode sorting is an essential function for optical systems exploiting the orthogonality of photonic orbital angular momentum mode space. The familiar log-polar optical transformatio…
Design and optimization of optical modulators based on graphene-on-silicon nitride microring resonators
Zeru Wu, Yujie Chen, Tianyou Zhang +5
In order to overcome the challenge of obtaining high modulation depth due to weak graphene-light interaction, a graphene-on-silicon nitride (SiNx) microring resonator based on grap…
A Highly Adjustable Helical Beam: Design and Propagation Characteristic
Yuanhui Wen, Yujie Chen, Siyuan Yu
Light fields with extraordinary propagation behaviours such as nondiffracting and self-bending are useful in optical delivery for energy, information, and even objects. A kind of h…
Tailoring Accelerating Beams in Phase Space
Yuanhui Wen, Yujie Chen, Yanfeng Zhang +2
An appropriate design of wavefront will enable light fields propagating along arbitrary trajectories thus forming accelerating beams in free space. Previous ways of designing such…
Winding light beams along elliptical helical trajectories
Yuanhui Wen, Yujie Chen, Yanfeng Zhang +2
Conventional caustic methods in real or Fourier space produced accelerating optical beams only with convex trajectories. We develop a superposition caustic method capable of windin…
