The 2 x 2 MMI-MZI polymer thermo-optic switch in a high refractive index contrast (0.102)
with a new structure design is realized. The fabrication was done using standard fabrication …

New types of UV curable polymeric ultra-long array waveguide true-time-delay (TTD) lines
for wideband phased array antennas (PAA) are designed and fabricated using direct UV …

The azo benzothiazole polyurethane–urea (ABPUU) was synthesized from chromophore
molecule 4-[(6-nitrobenzothiazole-2-yl) diazenyl] phenyl-1, 3-diamine NBDPD, polyether …

Azo chromophore molecule (NPMBR) was synthesized by using 4‐nitroaniline, sodium
nitrite and chiral reagent, R‐α‐methyl benzylamine. Then, NPMBR was polymerized with …

A Y-branched digital optical switch (DOS) based on silicon substrate was proposed using
the thermo-optic effect of polymer material and the performance of the switch was simulated …

A novel main-chain azo polyurethane-urea (MCAPUU) was prepared with chromophore
molecule 1, 1′-azobisformamide (ABFA), polyether polyol (NJ-220) and isophorone …

A polymer-on-silica Mach–Zehnder interferometer (MZI) TO switch is experimentally
demonstrated using core polymer material with large thermo-optic (TO) coefficient. In the …
