DESIGN OF DPSK MODULATOR AND DIRECT DETECTION RECEIVER FOR DWDM BASED OPTICAL COMMUNICATION SYSTEM [PDF]
ICTACT Journal on Communication Technology, 2016 In this paper a 16-bit differential phase shift keying (DPSK) modulator is designed for 32 dense wavelength division multiplexing (DWDM) channels. The DWDM channels are designed with 0.8nm separation in wavelength and operated at 4dBm input power. In the

Monolithic temperature‐insensitive high‐Q Ta2O5 microdisk resonator
Nanophotonics, Volume 14, Issue 27, Page 5475-5483, December 2025.Abstract We demonstrate a temperature‐insensitive high‐Q tantalum oxide (Ta2O5) microdisk resonator fabricated using electron‐beam lithography and inductively coupled plasma reactive‐ion etching. The microdisks exhibit a loaded Q‐factor of 4.25 × 105 at 1,550 nm, which more than doubles (∼9.3 × 105) following thermal annealing at 600 °C.
