Flattening laser frequency comb spectra with a high dynamic range, broadband spectral shaper on-a-chip
Nemanja Jovanovic, Pradip Gatkine, Boqiang Shen +9
Spectral shaping is critical to many fields of science. In astronomy for example, the detection of exoplanets via the Doppler effect hinges on the ability to calibrate a high resol…
Low bend loss waveguides enable compact, efficient 3D photonic chips
Alexander Arriola, Simon Gross, Nemanja Jovanovic +5
We present a novel method to fabricate low bend loss femtosecond-laser written waveguides that exploits the differential thermal stabilities of laser induced refractive index modif…
Cladding mode coupling in highly localized fiber Bragg gratings: modal properties and transmission spectra
Jens Thomas, Nemanja Jovanovic, Ria G. Becker +5
The spectral characteristics of a fiber Bragg grating (FBG) with a transversely inhomogeneous refractive index profile, differs con- siderably from that of a transversely uniform o…
