07th August 2024: Paper Presentation at the CLEO-PR 2024, Incheon, South Korea.

We congratulate our research scholar, Ms. Shruti Pandey, on the paper titled 'Extraction of Silicon Photonic Wafer-Scale Process Variability using ML-Enhanced Algorithm', presented at CLEO-PR 2024 in Incheon, South Korea. This remarkable work was accomplished through a collaborative effort with SilTerra Malaysia Sdn. Bhd. By employing GPR-ML models, the team successfully predicted sub-nanometer scale width, height, and effective index variations from the transmission characteristics of ring resonators at various locations.
Special recognition goes to Tarun Arumugham and Anjana James for their exceptional teamwork with Shruti in implementing the algorithm. We also extend our heartfelt gratitude to the other co-authors (Ashitosh Velamuri, Dr. Arnab Goswami, Yih Loong Gan, Chew Yan Ng, Prof. Deleep Nair, Prof. Anjan Chakravorty and Prof. Bijoy Krishna Das), whose active contributions were invaluable to the success of this work.


05th August 2024: Paper Presentation at the CLEO-PR 2024, Incheon, South Korea.

We congratulate our research scholar, Mr. Kumar Piyush, for delivering an outstanding presentation on "Estimation of Local Phase Errors in Silicon Photonic MZI Mesh from Passive Measurements" at CLEO PR in Incheon, South Korea!
His presentation underscored the critical importance of overcoming tapless detection challenges for advancing integrated programmable photonics. By employing a Particle Swarm Optimization algorithm, our team successfully reduced optical crosstalk by an impressive 30 dB in a 4x4 MZI feedforward mesh. The algorithms versatility can be extended to large-scale PICs in optical switching, neural networks and quantum computing applications.
We extend our sincere gratitude to our team (Kumar Piyush, Yash Raj, Akash Shekhar, Ashitosh Velamuri, Arnab Goswami, Prof. Janakiraman Viraraghavan and Prof. Bijoy Krishna Das) and collaborators (Naveen Raj Murugesan, Anandha Padmanabhan and Dinanath Soni) at izmo Microsystems for this remarkable achievement!


20th July 2024: Paper publication in Optics Express Journal.

We congratulate Ms. Pratyasha Priyadarshini and the co-authors (Dr. Arnab Goswami, Mr. Ashitosh Velamuri and Prof. Bijoy Krishna Das) on the publication of the paper, titled "Distributed Bragg Reflector Based ASE Noise Removal Pump Wavelength Filters for Futuristic Chip-Scale Quantum Photonic Circuits" in Optics Express.
For the full-scale integration of an integrated quantum photonic processor, it is essential to remove the broadband noise originating from amplified spontaneous emission within the chip. The major challenge lies in designing an ultrabroad passband filter with a high out-of-band rejection ratio. To address this challenge, the team developed a novel design for a compact tunable distributed Bragg reflector-based cavity.
This device, with a length as short as ~35 µm, exhibits a rejection band as wide as ~60 nm with an extinction ratio of ~40 dB relative to the resonant wavelength peak at λr ~1550 nm. The noise associated with an amplified pump wavelength (λp ~1550 nm) is suppressed down to the detector noise floor.

19th June 2024: Poster Presentation at the ECIO 2024 in Aachen, Germany.

Congratulations to Mr. Arnab Goswami for poster presentation of the paper 'Silicon Photonic Wafer-Scale Yield of Single Mode Resonator with Broadband DBR Mirrors' at the European Conference on Integrated Optics (ECIO) 2024 in Aachen, Germany.
Bragg grating-based devices have wide-ranging applications in filtering, switching, modulation, sensing, and more. While e-beam-based fabrication is reliable for creating Bragg gratings, the absence of Bragg devices in the device library of commercial silicon photonics (using Deep UV) PDK has hindered large-scale adoption.
In a successful collaborative effort between SilTerra Malaysia Sdn. Bhd. and Silicon Photonics CoE-CPPICS IIT Madras, we have made significant strides in integrating distributed Bragg grating-based broadband devices into the PDK of a commercial silicon photonics foundry like Silterra.
We extend our gratitude to all the co-authors, Pratyasha Priyadarshini, Gan Yih Loong, Chew Yan Ng, Prof. Deleep Nair, Prof. Anjan Chakravorty, and Prof. Bijoy Krishna Das who made this possible.
