Abstract On‐chip light amplification with integrated optical waveguide fabricated on erbium‐doped thin‐film lithium niobate insulator (TFLNOI) is demonstrated using the photolithography‐assisted chemomechanical etching (PLACE) technique. A maximum internal net gain of 18 dB in small‐signal‐gain regime measured at peak emission wavelength 1530 nm for a length 3.6 cm, indicating differential per unit 5 cm −1 . This work paves way to monolithic integration diverse active and passive photonic...
We demonstrate a C-band wavelength-tunable microlaser with an Er3+ doped high quality (~1.02x10^6) lithium niobate microdisk resonator. With 976 nm continuous-wave pump laser, lasing action can be observed at power threshold as low ~250 {\mu}W room temperature. Furthermore, the laser wavelength tuned by varying power, showing tuning efficiency of ~-17.03 pm/mW blow 13 mW, and 10.58 above mW.
The expansion applications of semiconducting polymer dots (Pdots) among optical nanomaterial field have long posed a challenge for researchers, promoting their intelligent application in multifunctional nano-imaging systems and integrated nanomedicine carriers diagnosis treatment.

We observe high optical quality factor (Q) polygonal and star coherent modes in a lithium niobate microdisk. In contrast to the previous polygon achieved by deformed microcavities at lower mechanical Q, we adopted weak perturbation from tapered fiber for mode formation. The resulting intracavity power of triggers second harmonic generation efficiency. With combined advantage Q cavity optomechanical oscillation was observed first time. Finally, frequency microcomb with an ultra stable...
Graphene has become an attractive material in the field of electrochemical detection owing to its unique electrical properties. Although simple stacking structures two-dimensional (2D) graphene sheets can provide excellent properties, a macroscopic three-dimensional (3D) structure needs be constructed enhance functional with 3D elegant functions, unlike 2D structure. These properties include large specific surface area, easy loading nanomaterials electrocatalytic and redox so on. Herein, we...
Orbital angular momentum (OAM) has gained interest due to its potential increase capacity in optical communication systems as well an additional domain for reconfigurable networks. This is the following: (i) coaxially propagated OAM beams with different charges are mutually orthogonal, (ii) OAM can be efficiently multiplexed and demultiplexed, (iii) OAM manipulated. Therefore, multiple data-carrying could have capability switching routing. In this paper, we discuss work involving OAM-based...

Recently, interchip/intrachip optical interconnection networks have been proposed for ultrahigh-bandwidth and low-latency communications. These employ the microresonators (MRs) to modulate, direct, or detect signal. However, utilized MRs suffer from intrinsic crosstalk noise signal power loss, degrading network efficiency via signal-to-noise ratio (SNR). The amount of loss may differ network. Hence, there exists a need systematically analyze effect issues. In this paper, we developed...
