The phrase "at the same wavelength" is correct and usable in written English.
You can use this phrase to refer to two people who are understanding each other without having to communicate explicitly, or who have a good connection with each other. For example: "We have been close friends for years, and it often seems like we are always on the same wavelength."
A diffraction efficiency of 1.5% is achieved for readout at the same wavelength.
The photoluminescence in solid or liquid medium occurs at the same wavelength.
The interacting signals are counter propagating in the semiconductor optical amplifier and hence can be set at the same wavelength.
The illustration below shows how signals from San Francisco and Cupertino arrive in Palo Alto at the same wavelength, both bound for San Jose.
Light in the feeble input signal stimulates excited erbium atoms in the fiber to emit more light at the same wavelength.
Rod cells are the most sensitive to light, but all absorb at the same wavelength, which does not allow colours to be distinguished.
And the crosstalk penalties from adjacent code channels (at the same wavelength) are found to be little in upstream and downstream transmissions.
Therefore, high transmission is achieved for the matched output port while high isolation at the same wavelength is simultaneously achieved for another waveguide.
Whereas, the forward- and backward-pumped single-pass amplifiers (at the same wavelength) achieved a maximum low-signal gain of 20.0 and 22.2 dB and a corresponding noise figure of 4.6 and 10.3 dB, respectively.
For near normal incidence, R = 51.1% @ λ = 6.65 nm could be reached with our La/B4C multilayer mirrors, whereas R = 58.1% was achieved with LaN/B4C multilayers at the same wavelength.
By optimizing the geometrical parameters of the structure, we can obtain an almost 10-fold enhancement of Faraday rotation with a corresponding transmittance 50%, and the FOM of 0.752 at the same wavelength.
